I owned a Wilkinson DR up until 2 years ago. Mine was
much earlier than yours. 577/.450 MH cartridge. Engraved
on the barrel rib was "Wilkinson & Son No.27 Pall Mall,
London". This is the famous sword and razor blade makers.
The underside of the barrels had numerous initials stamped
but nothing that matched Leonard's. It sure looked like
a W&C Scott built rifle.
Hope this helps a little.
