Carol's Guns

I collect old Winchester rifles. He said he had this Shiloh rifle that was MADE in 1874, one I had never seen before. I didn't have a rifle from the 1870s, so I bought the rifle and a SW 380. The receipt listed $3,500, $400 then $302, no description of what I bought. Once home, my research showed the rifle was made in the last 1980s. It is a MODEL 1874. I paid $3500 and it is worth $125. I'm 65 yrs old, I know better, This is my fault, I should have never taken his word, without taking the time to do some research. But maybe this lesson of being scammed will save me more money down the road. Carol is his wife's name, is there a reason? This transaction took place on 031320.
