Below is a thread on an early Beretta but I don't see a Rampant Lion but the term choke & its position is similar:
http://www.doublegunshop.com/forums/ubbthreads.php?ubb=showflat&Number=370845&page=1"Jim Bode published this last year. It is the 1940 catalog:
- Mod. 409bis 4 locks, receiver and tubes in Krupp steel, fins
- Mod. 409 PB 4 locks, Krupp receiver, “Prima Krupp” tubes
- Mod. 409E PB As above, w/ejectors
- Mod. 410 Piccione 4 locks, “Prima Krupp tubes”, special engraving
- Mod. 410E Piccione As above, w/ejectors
- Mod. 411 Piccione Extra 4 locks, stainless “Excelsior” tubes, sideplate, toplever gold pigeon inlay
- Mod. 411E Piccione Extra As above, w/ejectors
They were constantly seeking out sources for barrels. Krupp first appears in the 1930's."
