I do recall Searcy made some sxs rifles on B.C. Miroku Anson & Deeley actions the so called Browning Side by Side shotguns (BSS). I did see some smaller bore O/U rifles made by Olin Kodensha company. One I seen was .270/,270. There are some unique guns out there that is for sure. If the gun is well regulated then you "stole it".
