Hey guys, I lurk much much more than I post but I need your expertise.

I have an opportunity to buy this AyA for $300 but the seller knows little to nothing about it. 2.75" chambers, 26" barrel, C/IC and the serial # puts it as a late 70's manu date.

That said here are some sample pictures. Based on what you see is $300 a rip off, fair price, good price, or a steal?
