Wollensak 101mm f 4.5 Raptor lens in a Rapax shutter

Does anyone have one of these? Do you know what the slip on filter size is? Is there a series adapter that I haven't found yet? It appears to measure 32mm or 1 1/4". I may have to make something up from scratch. I would like to have a filter holder and lens hood that allows me to cock the shutter.

let me know what you have found for these threadless lenses.

Thanks,

Curt

I have one at home, I'll try to remember to ck it - but I suspect it's 31.5mm, that was a common size if I recall correctly.

Thank you much

Curt
