BP and campfire: #9356 over at GB is a Centaure Regular New Model Army (RNMA: 8" barrel, 3-screw frame, notches in recoil shield, traditional finish), 3rd variation (roll-engraved Ormsby style naval engagement scene with CENTENNIAL between the scene's ends), 3rd sub-variation (no toe on butt).
Incidentally, the naval scene was not applied at the Belgian factory but at the shop of their U.S. distributor Centennial Arms Corp in Lincolnwood, IL. Centennial Arms' owners believed their U.S. customers would not go for the Centaure proprietary naval scene (less background Details) but were used to the Ormsby Scene and would prefer it.
Ca. 2000 specimens were produced between 1964 and 1970. This one is from 1970.
To the best of our knowledge FAUL never installed anything but plain walnut or irory grips. Hence, it is my considered opinion the checkering is a custom job.
