I have a couple vactrols that I think I got from Smallbear a year or more ago that have no markings and I don't remember specifically which ones I might have ordered at that time. The only marking they have on them is a gold 'F' on one side. If that F doesn't mean something, is there some other way I can guesstimate what they are based on measuring resistance and matching up data sheets or something?
Doh! Just went make through the Nautilus build doc which is probably around when I picked these up. I think they are Macron MI1210CLF-R.

Edit: Looks like you figured it out.
