2 s. U.
 

I tried to do a search here for this unit marking and went through the post listing but did not see it. If it has already been discussed a link would be appreciated.

DWM 1910
Front grip strap Marked 2 S. U.
Sear safety
Mag safety (what remains of it)

I have been looking through Ed's book (love this book) but have not been able to find it.

Thanks in advance
