I have a .22 pump rifle that is marked TNFAC, Martel, I cannot find any info on it, looks just like a model 27 Marlin and the parts looks interchangable. Is this a Marlin manufactured for sale by TNFAC?
I think that DOC is getting you in the right direction. I did locate the following info that might be helpful to you.
Hopkins & Allen Established in Norwich, Connecticut in 1868, taken over by Marlin-Rockwell in 1917, and now owned by Numrich Arms Corporation and located in West Hurley, New York. Manufacturers of all types of sporting arms but best known for their early revolvers.
