Welcome to
SGW ! !
You've already ID'd your guns as Greeners, so what information would you like to find out ?
Pics, unfortunately, are the best way to determine the model.
(There's plenty of tutorials available online to describe how to post pics)
Failing pics, a description of all the markings stamped into the metal parts might help.
The areas to look for the marks are:
The action watertable flats
The barrel flats
The barrel undersides between the forend latch & the barrel hinge
The top of the barrel rib.
The Greener experts, however, can be found at
