nhglyn Posted September 12, 2003 Author Report Share Posted September 12, 2003 Another question! If a Lyman adjustable can be found, and purchased, do the holes line up with the ones that are on the 1927 A-1 of AO/Kahr manufacture? Can you just swap them, or do you need gunsmithing work to install the Lyman? Link to comment Share on other sites More sharing options...
The1930sRust Posted September 12, 2003 Report Share Posted September 12, 2003 Here's an image of the Lyman, too: http://www.darklightimagery.net/thompson/lymanrear.jpg The holes on the 1927 should line up with the holes on an original Lyman sight. Still, I'd HIGHLY recommend a compenent smith do the work. When I had an original sight added to my West Hurley, I thought of doing the rivet work myself, but it would have been difficult without all the proper tooling. I opted to have PK run screws up from inside, so the sight could be more easily removed if I was ever inclined to do so: Lyman attachment Also, here is another Lyman image: Lyman top Link to comment Share on other sites More sharing options...
PK. Posted September 12, 2003 Report Share Posted September 12, 2003 The hole position on all Thompsons, old and new is the same, however the types of attachments changed and can create challenges in adapting old sights to new guns. The original attachment was with 1/8”solid steel rivets. This gave way to 1/8” hollow (Pop) rivets, and finally (on recent production) M4mm screws with the threads in the receiver. These latter attachments are larger in diameter that the older ones. To install an old sight without modification onto a new receiver you need to make special stepped rivets. Alternately, the sight can be modified to accept the screws, but the value of the sight usually discourages this approach. It is difficult to do a proper rivet job without the right tooling.

giantpanda4 Posted September 14, 2003 Report Share Posted September 14, 2003 Hey Lionhart! Are you letting out a secret why one of your 1928 lower frames on Evilbay has weld beads on it??? http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/ph34r.gif I think I'm onto something here.....!!! http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/biggrin.gif Link to comment Share on other sites More sharing options...
