I have a Llama in .32 acp. Looks similar to a Colt M1911. Forgot I had it until this thread. I bought it in the early nineties and only put one mag though it.
here is a WW bring back .32. Not sure if it came home from WWI or WWII
I think anything that might help determine that would be on the side not pictured
If there are markings on the front strap or you can narrow down which variant it is from the detailed article below, that might answer your question.
