Butt Slide Types

[Brit plumber]

I have seen a Lithgow MK1 gun No 24 i think it was. With matching lower that had the same intricate machining around the trigger axis pin as the early enfields had.There must have been a rapid change to the profile of this area same as the later MK1 slides because mine is No124 with matching lower that is simplified.

Very intresting, I have A123 and A128 and they also have the simplified lowers. I've some pics somwhere of a Early Lithgow, I think its A3, I'll see what type of lower it has. Have you also noticed the correct early Lithgow bipods have a slightly larger hole in the feet and the radius of the flat portion (rear of foot and on the inside of the gun) is much larger than the Enfield and Inglis types?
