I was at a sale recently where they this up for sale, for the lucky holder of masses of correct paperwork. Made around £950 I believe.

Nice to see one in general ownership. I hope it works well for you. All the questions on originality should be answerable in the retro section of AR15.com.

You might like one of these for your local range? They aren't bad, although not as well made as many of their other products. Decent ones come up at under £200 sometimes. Good fun for the price, particularly with what the current pot-metal versions come in at.
