Aircraft ammunition (20mm, 27mm, 30mm)

Please click on any of the thumbnails below for viewing a larger version of the same image. Unfortunately the scans did not come out very well, where possible I tried to correct the colours so they would look closer to the original colours. A lot of the bullets which are not shown here, or which are only shown without paint, actually do have blue paint on them. Finally, in most of the pictures I added a ruler so the size of the bullets and the casings becomes a bit clearer.

30mm:
		Markings on the bullets (from left to right): RG74, [illegible], [illegible], RG84, RG85, RG86, RG, RG86, RG85, [illegible], None. Notes: This picture has one sample of all the different 30mm bullets I have, they are mounted on the casings (all casings are otherwise empty). The RG84, RG85, and RG86 bullets are basically identical (apart from the numbers (= year of manufacturing?)) all the others differ in at least one shape aspect. Gear used: Olympus OM-4Ti + Zuiko 50/3.5 Macro (@f16) + T28 Twin Flash. Distance indication on lens: 0.7 metres. Digital edits: Gamma correction +1.80 to make the colours/contrast look more like the original slide.
		Markings on the bullets (from left to right): RG74, [illegible], [illegible], RG86. Notes: This is a close up to show the shape differences between the various "RG-marked bullets" in more detail. Also, note that I showed the most damaged/worn versions of each of these bullets, I don't have any bullets which are in worse shape. Note the oxidation and dents, as far as I can tell from the damage, at least the RG86 one seems to be a full metal jacket. Gear used: Olympus OM-4Ti + Zuiko 50/3.5 Macro (@f16) + T28 Twin Flash. Distance indication on lens: 0.45 metres. Digital edits: None.
		Markings on the bullets (from left to right): RG74, [illegible], [illegible], RG85. Notes: This is a close up to show the shape differences in the bottom parts of the various "RG-marked bullets" in more detail. Note hw the RG85 (and RG84 and RG86) ones have a round bottom part, whereas the RG74 one is completely flat, and the other two are flat, but with a substantial (about 1 CM deep) indentation. Also, note the wear on the two illegible ones, I believe these are the two oldest bullets I have. Gear used: Olympus OM-4Ti + Zuiko 50/3.5 Macro (@f16) + T28 Twin Flash. Distance indication on lens: 0.3 metres. Digital edits: None.
		Markings on the bullet: [illegible] Notes: This is a close up to show the worst oxidation that I could find on the 30mm bullets. Note the regular rusty oxidation, as well as the white-ish oxidation on the lighter coloured (aluminium?) tip. I have only very few bullets which are this badly oxidised (maybe some 3 or 4). Gear used: Olympus OM-4Ti + Zuiko 50/3.5 Macro (@f16) + T28 Twin Flash. Distance indication on lens: 0.23 metres. Digital edits: None.
		Markings on the casings (from left to right): Nr: Bottom: Side: Colour: 1 30-550 AA 9 -MR- 82 30 mm TP DEFA M43 LOT04 FNB82 Silverish 2 30-550 AA 8 -MR- 82 30 mm TP DEFA M43 LOT03 FNB82 Silverish-Goldish 3 30-550 AA 8-TE-86 F2570-23-ATE-86 Dark army green 4 30-550 AA 10-TE-87 F2570-28-ATE-87 Dark army green 5 None. CY 170 63 HE TX 5 52 30MM RG-61 Yellowish-Copper 6 None. 954 CY 86 PRAC 4Z J30MM RG-86 Copper Notes: This picture has one sample of all the basically different 30mm casings I have, the most common kinds are nrs 1, 2 and 6, the others are much rarer. I have several ones of each of them and the markings between similar kinds vary only very slightly (probably only to indicate a different production batch and a different year of manufacturing). Note that on nr 6 the text "PRAC" (= practice?) can be found, as well as an "RG number" (= year?). By far the majority of casings and bullets I have seem to be from the years 84-86, nr 5 (of which I have only one) may date back to 1961, the green ones I have (some 5 in total) all indicate 85, 86, or 87, nrs 1 and 2 appear to be from 1982. Finally, note how all these casings are "completely straight", in other words, the top part does not have a nozzle, as is the case with the 20mm and 27mm casings pictured down below. Gear used: Olympus OM-4Ti + Zuiko 50/3.5 Macro (@f16) + T28 Twin Flash. Distance indication on lens: 0.4 metres. Digital edits: Gamma correction +1.80 to make the colours/contrast look more like the original slide.
27mm:
		Markings on all the casings: Bottom: Side: Colour: 27x145 DM1001 LOS DN-1-37-X None. Greyish metal Markings on the two bullets: Nr: Bottom: Side: 1 (bottom of the picture) None. 27k DM18 LOS RG-1-6 DM1086 2 (top of the picture) None. RG-1-6 (any other text that might have been there is illegible) Markings on all the shackles: Inner side: Outer side: Colour: None. MK2 R.G. Black painted metal Notes: This picture shows a few of the many 27mm casings I have, all are of the same kind and have similar markings. All the shackles also have the same markings. Also pictured are the only 2 27mm bullets I have, the bottom one is in best shape (i.e. the one with all the markings). The other one seems to only have part of the markings left (I can't make out any trace of further markings than the ones mentioned), and this one seems to have ricocheted off of something which was very hard, as the tip is damaged. The damage seems to reveal that these bullets are full metal jackets. Gear used: Olympus OM-4Ti + Zuiko 50/3.5 Macro (@f16) + T28 Twin Flash. Distance indication on lens: 0.7 metres. Digital edits: Gamma correction +1.80 to make the colours/contrast look more like the original slide.
20mm:
		Markings on the casings: Bottom: Side: Colour: None. 20MM M103 NWM87J501-010 Copper None. 20MM M103 NWM-1-42-76 Copper None. 20MM M103A1 RNO79K521268 Silverish Notes: This picture has one sample of all the basically different 20mm casings I have, apart from the really rare slimmer ones (I will have to check if I can find these casings again, anyway, they seem to be old (+/- 1943)). Basically, the ones pictured come in two kinds, being the copper ones, and the silverish metal ones. All of them had the numbers printed in black on the side. The first mentioned markings on the copper one, as well as the markings on the silverish ones are slightly hard to read, so I may have gotten 1 or 2 numbers/letters wrong there. The only two 20mm shackles I ever retrieved on the field are the rusted ones (on which I could see no trace of markings), I believe the smallest of them may have belonged to the slim 20mm casings. Note especially that the other pictured shackles were not retrieved from the field, instead, they were given to me by a friend and they come from a different source (perhaps the aircraft that used them (most likely an F5 or an F16) didn't "waste" them?). The markings on these shackles are: MFT-1-51 M12. Further note that none of the 20mm bullets is really damaged, and that the majority of them still have blue paint on them. Gear used: Olympus OM-4Ti + Zuiko 50/3.5 Macro (@f16) + T28 Twin Flash. Distance indication on lens: 0.6 metres. Digital edits: Gamma correction +1.80 to make the colours/contrast look more like the original slide.

I hope you can help me out a bit in identifying which type of bullets/casings/shackles are pictured here, as well as what type of aircraft fired them, and if there is any potential danger in handling any of these bullets, or that they are completely inert. Thanks in advance!
