Will I need a recessed lens board?

[ThePhilosopher]

I bought a cheap lens on eBay (Wollensak 75mm f/1.9 Raptor in an Alphax shutter) and don't know if I will need to find a recessed lens board for my Sinar A1.

This lens has been talked about here before so a search will give you some answers. In short, I regret, it is an oscillograph special purpose lens which is not considered of use for LF.

Westley might be able to make it work on his Bronica.
