Thank you englishman_ca for doing what you could to date those receivers.
It's a little disappointing to know that they're not pre world war one but still cool to know something more than I did.

Hoping to get the order away for the sights this coming week. Financial constraints...

Some progress on the duplicator:

Notice that ive made the router mount adjustable in three places over a 50mm range. The follower will also be adjustable.

Sooner or later I'll get to do some work on the actual rifles!

That said, I'll probably spend less time building this than I would carving the stock purely by hand...
