LE #1 Butt Plate -- Different sizes for different length butstocks?

[Patrick Chadwick]

The butt plates are generally all the same for both No.1 and No.4 rifles (one of the few parts that are interchangeable, from what I understand).

Well maybe I've got some funny Enfields. But (at least on my examples) the No.4 butt is "chubbier" than the No.1 butt. And the tang on the No.4 buttplate is also a bit wider. On the No.1s the tang is somewhat "pointier". The difference is small, but the tangs on the No.4 plates will not fit in the cut-out in the No.1 butts, and if I put a No.1 plate in position on a No.4 butt, there is an ugly gap around the sides of the tang.

It would be enlightening if someone could make the same test and confirm/contradict my observation.
BTW, my Enfields are in ex-factory configuration as far as I can tell, with the exception of the No.8 fitted with an No.4 butt.
