Hello Hunterrod. I have been holding back waiting to be entertained by other answers. Your rifle is a post war composite. That is a rifle made up from the parts of others. The maltese cross stamp in your fore is the Long Branch sniper rifle dept. inspection stamp. So that fore was originally fitted to a No.4T. LB. That stamp was applied to 3 parts of the sniping rifle. Pg.27 in "Without Warning" by Clive Law illustrates the stamp on the fore and on the (converted) Mk I sight. I won't disclose the final part. So your fore is valuable to those small few who are making LB sniper forgeries. I enjoyed the attempts to link it to the Greeks but in truth it is a stamp unique to only one wartime LB department.
