Right now, I can’t supply photos although I have a big collection of .32 auto (about a thousand specimens). Just have other things on my mind and many other things I have to do. However, your basic question would be hard to answer completely. Just about every European ammunition maker who ever made .32 auto ammo used, at one time or another, cupronickel jacketed bullets. The popular jacket materials are generally titled as follows by collectors:
CNCS Cupronickel-clad steel
GM Gilding Metal
GMCS Gilding metal-clad steel
? Tinned steel (not sure if this was use, or how much, quite frankly. Would have to check my collection, and just don’t have time right now.
I would say that CN, CNCS and GM, GMCS were the most popular with European makers before WWII. Brass jackets were know, for sure, and used often by some. In recent years, brass jackets are becoming almost the norm, even including the USA where they were seldom used before the war, if ever (again, I’d have to check on that). Tinned jackets were not, it strikes me, as popular in Europe as they were in the USA, where after WWI especially, and some before, they were very popular until replaced primarily by GM bullet jackets. Again, recently brass is getting popular, and may even represent imported jackets. The ammunition business today is extremely “incestuous.” You can’t hardly tell all the players without a scorecard, in this case, box labels and the like that tell where ammunition is actually made. A label associated with a given country, say “Fiocchi” of Italy, does not in any way guarantee the product is from that country, or that if cartridges were loaded there, that all the components came from the same country.
Very complicated and the list you ask for would include 3/4 of the ammunition makers of the 20th and 21st centuries.
Sorry I can’t, at this time, give you the specific answer you asked for. Perhaps someone else can.
