You will probably find that it isnt metric. My old Wollensak lens wasnt, anyway. I used the closest metric step-up ring and filed down the threads until I was able to force it on (permanently). I can now use my 52mm filters on it.

According to my records, this would require a 48mm adapter. I'm not certain if that would be a slip on or screw in type. However, if you get a metric ruler and measure the OD you should be able to make that determination pretty quickly.
