KK, there is a Leonard number on the forend loop that is different from the Jeffery number.
As for the bow back, it is not necessary for the gun to be made by Leonard.
I have seen straight backs, circular backs (for the lack of a better wording) and notch backs from them.
I look at the general action style for more information.
Leonard guns have typically a round doll's head with some times but not very often a 3rd bite.
The general shape is quite different from a Webley or a Wilkes.
The action is on the short side (compared to Webley) but quite beefy.
Barrels are always chopper lumps.
Best regards,
WC-
