I think this thread is worthwhile resurrecting. Lots of nice examples from all eras.
I am adding my latest addition. An 80s 14-4 with SAO hammer. I bought it as being shipped SAO from the factory, and the box seems to support it. Doesn't really matter to me if it has been converted after the fact, as I got a really good deal on this gun. You can see, it is like new.
