Looking at your pictures the lens is in a Sinar DB shutter, which I am not familiar with.
A Compur 2-X tube 5/I has a 35mm front opening edge to rear opening edge
A Compur 2-X tube 5/II has a 25mm opening to opening
and both have a 45.8 mm opening.
You will probably have to have adapters made to fit the lens to current shutters unless you come across an older shutter that the lens barrels will fit and provide the correct spacing between groups.
The shutters are CN-1408-012 and CN-1408-013 in this service manual
