yup... only the top .50 are WWII... From left to right, top to bottom on the above page, the cartridges are: 1. “M860″ .50BMG tracer (range training cartridge). 2. Unknown dummy, 3. Wood bullet load (hard to tell caliber, these are not to scale), 4. HSA “Cobra” multi-dart 9x19mm AP load (British, and short-lived), 5. Israeli 9x19mm shot load in resin matrix, for riot use, or anti-skyjack use, 6. Unknown ball load, looks like .32acp or 9×19 (not in scale), 7. Solid brass hollow point 9x19mm, one of many Euro experimentals, 8. “ZM75″ 7.62 Czech short-range tracer loaded into .32acp case for use in the RPG-75 launcher, 9. Glaser Safety slug (blue, #12 shot) – probably .38spl, 10. Probably a .224 BOZ, or a .225 JAWS, 11. 4.6x30mm RUAG “DM11″, 12. probably an XM216 flechette, 13. Colt .308 project SALVO exprimental, 14. probably a .455 Webley ball load, 15. Speer plastic indoor training load – .38 cal. *** These photos are excellent, but when shown side-by-side are often out of scale relative to the neighboring cartridge. Only a couple of these were around for WWII, but perhaps many of the photos taken but not shown were from that era. The sections were most likely done by Paul Smith or Reinhold Peschke for whomever the Swiss collector is (maybe Reinhold himself) – fantastic sections!
