That sort of depends on whether you agree with Wallace Guslers attribution of RCA 42.
Rifles included are RCA 17, RCA 42, RCA 46, RCA 48, RCA 53, the 2 lion carved rifles, the griffon carved rilfe by Oerter, and a beautiful smoothbore I have only seen before in Shumways longrifle articles Vol 1 page 48. This smoothy has a keyed toeplate I have only seen before on Oerter rifles.
