No, their outlines are identical. And symmetric.
I've looked through the cupboards and as it turned out, I had more variety of F/F2 finders than I remembered -- maybe I'm getting a bit old in the tooth? All versions of the DP-x finders are present, apparently. Plus 6X loupe and action finders, in addition to the plain/T prism finders and 6-7 F2 bodies -- most black, but one 'panda' stands out. It had slipped my find there were so many of these items. Oh well. Maybe time to arrange a garage sale?
