Thank you gentlemen
I have asked that the gun be sent back to me and will take some photos and get in touch with Mr Merrington as soon as I have some detailed info and photos for him.

Frankly, I dont know if the gun is worth it apart from the sentimental value...Google doesnt tell me much apart from the man who made it also owned the factory it seems (P.Lorenzotti) is engraved on the right barrel. Receiver is color case hardened and looks a treat.

Thank you both again.
