Just tried it and the tube could be screwed in the flange of the "Russian Elmar" Industar.

The Industar flange also seemed the tiniest bit thicker so I don't know about focus inaccuracies. Both turn about 180 degrees from infinity to 1m, so I assume the distance scale would be about OK.
Industars are nice lenses and cheap to get. Worth a try to get one and try fit the flange on the Elmar. If it doesn't work, you could always use the Industar on your LTM bodies.
