Thanks to Lagopus and Salopian for posting pics. The gun in question has been left to someone I work with here in Niagara region Canada and wants to know approx value. There are more pics available but I do not know how to post hence the Trans-atlantic connection. The serial # is 130471 it is also marked .729 and BNP 12 2 3/4 3 1/4 tons.I have not seen gun but in some of pics there seems to be a rust issue. If someone wish`s to post other pics for me my email is pedler151@cogeco.ca.
Thanks Again Pedler
