This is my .303 Browning MkII from 1939. I'm hoping there may be some one on the forum with a relic or deac MkII who could help me out with some dimensions of the barrel cooling jacket. I've now got the dimensions for the cooling slots, the narrow end, the wide end and the thread type. What I could do with is the dimension for the length of the jacket or between 2 points i.e. back of the booster to the face of the trunnion as I could work it out from that.
Also, would anyone happen to have a trigger plate for the MkII which slides under the rear of the gun and works of air pressure?
