Thank you, Mike for the help and thank you all, for the kind words about the guns.
These are YOUR guns, Eric.  They’ll always be your guns.  I’m just holding onto them for a while.
     Good luck out there, everybody!

Very nice set.

Not much out there about the Geiger.  This is the best info I found.

Again looks a lot like a 1911 lower end with a redesigned locking/recoil system.  It really resembles the Korth a lot.  The biggest difference is the takedown system.

Correct. I had contacted Loctite at the time when grip screws were "a chore" for most people, even me, to loosen them up without damaging them, the grips or the frame. Their technician mentioned it was an easy fix. . . . . Loctite turns to a liquid in the item you're working on around 300 degrees. Use a soldering gun with a pointed tip installed, put it onto the Allen screw head area for a few moments (3 - 5 seconds here) and the material turns to a liquid again and you can easily remove the screw. I love that whenever we contacted any vendor about an issue, they were always very helpful with their answers. It was a great industry for Karl & I. 

Here are the guns Chris is posting about.
