The Garcia booklets from 1968 has the basic info. The S2 was the entry level of the SO line which encluded SO3,O4,and O5s. The SO2 had regency grade engraving with a silver dove inlaid in the opening lever. They were not off the shelf shoyguns during the Garcia era. Each one was special ordered with customer desires. This is the main reason you may see many variations of the older models. The entry price for the SO2 was $800.00 in 1968. Two importers were noted on the earlier Beretta SO's, one was Abacrombi and Fitch(SP) and Garcia.They are fine sidelocks and will out live us both.(IMHO) Rich Cole can make most repairs if the need should come up. He has said he might not do any rust blue on the SO barrels for a while but, that could change.
Best,
