I've come across a CVA mountain rifle but I'm unsure of the specifics. I believe it has a Deer Creek barrel on it as it just says Connecticut Valley Arms Inc, Black Powder Only 50 Caliber. It doesn't say made in USA or Spain and there are no Spanish proof marks etc. It also has a pewter nose cap and looks like Deer Creek trigger guard. I'm unsure of the time period this rifle might be from as well as did Deer Creek make these rifles or supply parts to CVA? I assume they are better than the Spanish made CVA?
