Surprise short pinion/ 6-40/ "round" lock bar rear sight.

[RCS]

My friend in NJ paid $600 to Debbie M for a Type 1 lock complete rear sight assembly and my friend in Calif said they were as high as $900 for a complete assembly.

When I was an armorer I found some Type 1 lock bars which I took with me as everything used the type 2 & 3 lock bar except the sniper rifles which were all H&R M1D

I even found a Type 1 lock bar that some GI forced on a type 2 long pinion and crossed threaded the lock bar !

WOW! That was one determined GI...to thread a 6-40 lock bar on to an 8-36 pinion.

On the Type 1 that I have, the "Battle Range" triangle lines up with the 300 yd. mark on the elevation knob. Is this correct?? So far I have been unable to loosen the screw that holds the 2 parts together. Is this screw a normal RH thread?

Yes, it is a RH thread.

Yes, it is a RH thread.

Thank you. After a couple days of heating with electric heat gun & penetrating oil...and some judicious application of force, I was able to get it apart & no damage. I don't think it had been dis-assembled since WW2.
