Are Doran and FR tanks the same thing ?
Never saw one in real life, so I must ask.

Yes.

Doran is later, not sure when Fink-Roselieve went under, but in looking at a couple of Doran tanks, it's pretty obvious they are using the same molds and machined out "FR" and machined in 'DORAN" a little deeper.

Two words of caution. the lid is made of THREE pieces: the cover, the light trap and a bar. If you don't have all three it won't work.

Two: if you use a straight developer, poor it in, in the dark, then add the lid. You'll have less change of streaking the film this way. With dilute developers or pre-wetting the film, it's not as bad. The Yankee and HR tank has the FR tank beat in this regard as they use removable baskets and one piece lids.

For the fr tank, the manufacturer suggests a side-to-side agitation. I have been using one of these tanks and have noticed a tendency to have uneven development (that is streaks on the negatives). A side-to-side agitation with a tipping motion at the end will prevent this problem.
