    For those in the anorak seats, I found the included angle of the thread on a No1 Bolt head:
    79 degrees, 30 Minutes. It is depicted as a triangular thread with notes and tolerances for the form of the root and crest. There is actually a "Go" and "No Go" gauge, both of which are "adjustable to master "plug" gauges by means of a (lockable) screw, not unlike as found on thread dies. NO CMM gizmos in those days.

    This is taken from Lithgowicon drawing C 4983, dated 20 October 1944 which has, hand-written across it: "Superseded. See Data Sheet DS 464, Sheet 410-3-52". This was, in turn, a revision of a 1935 version of the drawing.

    Thus, Lithgow fine-tuned some gauging in the process of doing the last ever run of No.1 Mklll* rifles at the factory.

    Sadly, i do NOT have this later drawing in the "crypt".

    A Collector's View - The SMLE Short Magazine Lee Enfield 1903-1989. It is 300 8.5x11 inch pages with 1,000+ photo’s, most in color, and each book is serial-numbered.  Covering the SMLE from 1903 to the end of production in India in 1989 it looks at how each model differs and manufacturer differences from a collecting point of view along with the major accessories that could be attached to the rifle.

    I think what 5thBatt might mean here is that one does not run across that many swivel screws that are so heavily staked that they ruin the threads of the outer band upon removal. (?)
