I have two rifles with the Type 1 lock bar which was a replacement for the "flush nut" but really did not
work out and had a short service life. Always difficult to find on a rifle and some have been faked by the
installation of a sleeve with the early thread on a Type 2 lock bar. Original Typ1 rear sight groups are
over $600 now.

I have a 38K with a S-A 10-41 barrel with a Type 1 lock bar and a June 1942 rifle also with the Type 1
lock barP1010054_0051.jpgP1010055_0052.jpgP1010024_0020_020.jpg
