I had seen those Jolo boards as well with the comment about teflon tape. So it seems like they may be close but not identical. I think to make things more confusing there were a couple of versions of this lens. Mine has a detachable flange but apparently some did not. I have the proper flange for my pentac but it is just way too big for the graphic lens boards.
I'll PM you with some info and see if it is doable. I am thinking if they are close, it might be possible to use the same board with a slightly different retaining ring.
Do you have some more lens bboards for aero ektar left? I want one for my Toyo Super Graphic. Please send e-mail to
I'd be interested in a board for a pacemaker as well.
