Per Tim : A custom Ruger #3 single-shot in .22 Hornet, manufactured in 1976. The extraordinary custom stocks make this little single-shot carbine a beautiful piece of gun art. I tried to find who the master stockmaker was that created them but nobody knew. I took the forend and Neidner butt plate off and found the stockmaker's stamp on both stocks; it read "Mike Conner". I tracked down who Mike Connor was and it turns out Don "Mike" Conner was born in 1931 in Grainola, Oklahoma, a proud member of the Osage Nation Tribe. He served in the Army during the Korean conflict and later graduated from Oklahoma University School of Technical Training & Drafting. He and his family lived all over the west and Alaska, and Mike died in Hurley, NM, in 2018. His obituary said he had a passion for crafting rifle and shotgun stocks and was ranked number five in the U.S., according to an old article in the 'Albuquerque Journal'. Stockmaking was his hobby and I estimate he was active from 1960’s to 1990’s.
