That is a 11124/OESBO (later version 11126)* which is a 90/2 in short 
mont for the Viso 2 or 3. Just the short mount itself is a 
16463/ZOOEP**. You would need to unscrew the optical unit and attach it 
to a (properly calibrated) rangefinder coupled focusing mount which may 
be well nigh impossible to find on its own.
