Hello folks. Thank you for welcome notes on and off list from Marc, Jon, Elias and Ken. I actually solved my first Rolleicord puzzle by searching the archives. So I didn't even have to post. Thank you John Wild, if you are out there. Now I know precisely what the differences are between the Rolleicord Va 16exposure set and what I need for my Vb mod 2. Does anyone have the Vb kit with thin masks to insert under the screen? Do the masks move with the parallax correction frame? Everything else works fine so I guess I should be able to make up some drop in masks. Cheers Hoppy Rollei new guy.
