My First Swiss 06/24

[Mac Cat]

Parabellum A Technical History of Swiss Lugers by Vittorio Bobba (1996) is what you want. It was written in two languages Italian / English side by side.

It's still available, but surprisingly expensive ($1,600 ??).

There is also Fred Datig's "MONOGRAPH IV: The Swiss Variations 1897 - 1947", which is more like $50. I bought mine here from another collector.
