Good news, J-PD,

Anticipate the book with pleasure. Would be willing to provide hi-res digitals of my Dicksons with the original Damascus barrels (rebrowned by Dickson in 1986) including (if I can get it) some rivelling near the chambers) and the new set of Italian steel barrels made by another a few years ago with modern London proof marks. Can PM me.

Yes, found the details, especially about the trio likely on the bench the same time as my gun No. 2, very interesting.

Regards, Tim
