Giorgio Becucci is the manufacturer and the V. Borgo 2 is the address for the company - there is a U.S. Patent from 1965 under this name but it is for a different box (United States Patent 3,390,809 "CONTAINER FOR JEWELS" Giorgio Becucci, Via Del Borgo 2, Bologna, Italy Filed Oct. 21, 1965, Serial No. 506,143). This Omega Box appears to be an ABS polymer plastic (so post 1946 ) and not a bakelite or catlin plastic. I'm sorry I can't do much more than that - and you may already have this information. It may not have a US Patent and instead hold patent rights elsewhere.
