4seventy your eyesight is excellent! With a 10x glass I can see clearly that you are right and it is indeeed Jean van MAELE

Hopefully kuduae may have something on him

Having googled it as you suggested there are a couple of examples - a single shot and a revolver recovered from the river Thames, both very cheap looking

Also a post on www.doublegunshop.com I cannot access

Kamiloroi - the locks appear to have been stoned as well as the general refinishing

What is the oil penetration at the back of the top tang please? I cannot see it

How do I do a chamber cast with what is available in the uk?

All 3 450/400 cases chamber, I went for the 3 1/4 inch as I thought as the shoulder is further forward than the 2 7/8, and less forward than the 3 inch, which is a very tight fit, as well as being developed later. I will of course now check the other calibres mentioned

I would obviously appreciate Capt. Curl and others comments and opinions

Many thanks to you so far
