Lots of stoves looked like fishers. Maybe Coaly can identify from this alone but the doors should put the question to bed.
For 65 bucks, that unit would need to have every weld checked, all sides checked for warpage, firebrick most likely replaced, make certain the insurance company is OK with covering the home once installed, and if that fails, you'd probably get about that in scrap value I'd guess.
If you look at the ash fender it has the channel around it. That was not easy to do I would say it was a fisher. Just for that. People copied fisher all the time, but I do not remember anyone coping that part. If your buy it and want to put a new back in let me know. I can talk you through it.
