And IMHO it would be a shame to salvaga a SuperIkonta-cousin for something like this - the Moskvas are up to good results with their Tessar-derived Industar lenses.
I have a Moscva 4 and I agree, it would be a shame to modify it.

But, for $28 you could get a Moskva 2 from Fedka.com that has a bad rangefinder. You don't need a rangefinder for a pinhole camera!
