How to build a tessar lens with prontor shutter?

[dafatduck]

I have a 150mm f/3.5 carl zeiss lens (it comes in 3 pieces) and I prontor SVS shutter. How can I reasonably mount the lenses to the shutter?

The issue is the size of the shutter, specifically the threaded opening. If it matches your Tessar lens mount, most likely it is a simple matter as usually Prontor and Deckel/Compur used the same basic shutter dimensions.
