Uncoated LTM 50's?

[wlewisiii]

I've been thinking about a prewar uncoated 50 to go with my prewar 90/4 Elmar. The 50/3.5 Elmar is, obviously, the most likely though there are a couple of other Leica lenses as well. The Summar comes to mind, for example.

However, what I'm curious about at the moment is if there were any other makers of uncoated 50's for LTM that are other than highly priced collectables?

Thanks!
