Peter;
What a great project you have there. After it is done, what a prize this will be. Multi barrels, great calibers.
I have some project guns to work on, but never have the time or the resource to work on them so far.
Best to you and your Alex Henry. Can't wait to see the shooting result.

I will be a little south of you this week in Rotterdam. Business though.
Any Shops there I might visit that may have some nice guns to look at that you may know of?
