Re: Re Proof Mark (crown over R)would have been considered redundant if submitted for proof as "SLEEVED" and so marked.
I don't believe Belgium provisional proof would have required bore dia in 0'1 mm increments at provisional proof .s
If it had been sleeved in Belgium and prooved there should be a Belgium proof mark on the action as well.
I doubt the economical viability of sending a gun from the UK to Belgium to be sleeved then returned to Birmingham for Proof.
I'm a little bit in the dark on this as I can only see the first photo on the original post.
Interesting tho'
