Lee Enfield Sights (Slideshow)

[muffett.2008]

Just to throw another rare one at you, Stan Edwards 1924 patent 17,575/24 complete with equally rare Central patent 143,379 peep.

Now at first sight you will note features of both Mues and Motton, but thats where the similarities end, Mues style Elevation lock knob although different in the patent - may be a replacement.
Motty leaf spring for windarm. This one has additional plate to tighten spring, not that it needs it when set correctly.

This is the second I have seen, this one has the patent number ground off the mounting point, but has Edwards stamped on the inner face.
