So I found a pair of Wolber Profil 20 rims on ebay and I was thinking of using them to build up a set of wheels for a track bike I'm working on. I tried to do some research on these specific rims and came up with little. I was wondering if you guys had any thoughts.

Dude, good so see you at classic and vintage. I don't see why you shouldn't use those rims, they are very nice, my only concern is they do not have eyelets which means you will need washers. Now these are a semi aero rim which might mean they use special proprietary curved washers.

Heh, good to see you here too, not surprising though. Are washers for these rims hard to find? Any clue on cost?

Thing is I don't actually know. I have had aero tubulars of that era with special washers so that was sort of a warning. Perhaps these would be ideal? https://cgi.ebay.com/Tubular-rim-nipp...QQcmdZViewItem

Also I have a wolber profile 20 (an there's one upstairs at bike doc. broadway)... I don't recall there being washers in the one I have. I'll go check it later today and report back.
