Ektar 203 f7.7 hole size for flash supermatic shutter?

[Nathan67]

Hi.
I have an Ektar 203mm f7.7 in a flash supermatic shutter dating from 1958. I really like the look I get from this lens and would like to be able to use it on my shen hao (right now it is on a crown graphic lens board) as portrait shots with the crown in the studio is
a non elegant process.

Does anybody know if this will fit straight into a copal 0 or 1 lensboard? or do I need to get all DIY... (hopefully not coz I have 10 thumbs...)

I dont really want to remove it from the graphic board just to try if I dont have to, hence the post.. I have searched around and cant find an answer..

Many thanks,

Nathan

Mine fits in what I believe is a Copal 0 board (don't quote me on that though), measure it and see what it is closest too?

copal 0 is fine.

great, thanks!

My impression is that the Supermatic mounted ones will NOT thread into a modern Copal, but that Compur-mounted/Prontor-mounted/ Euro-version ones with "Mount 370"/ will be a direct fit.

My supermatic mounted one does fit, but I think it is a little tighter than a Copal 0 shutter would be in there. My experience has been that the holes tend to have a little play.

Somewhere on the internet I remember a 1 1/2" hole requirement. I have no clue if that's a Copal 0 hole diameter. Measure the shutter O.D. and tell us what it is. I'm sure somebody here knows the I.D. of the hole in a board for a Copal ) shutter. Then we'll all know. I hope y'all are right. I have two boards with Coapl 0 holes. I already have 1 Supermatic shutter for the 127mm Ektar, and look forward to owning the 203mm Ektar one day. It would be nice if I already have the board for it.

great, thanks!

As said, it sits nicely in my copal 1 lens board. Live well.

Oops, sorry, didn't read closely enough before my earlier post to see that the OP was referring only to the opening in the lens board. (For some reason, I'd thought he was trying to replace the shutter itself with a Copal.)

Thanks everybody for the help
Just to clarify, it was the hole size in the lensboard that was of interest, I have a lens tool that fits the other lenses I have, but not the retaining ring on the ektar, so before getting a tool that fits, and a new lensboard I did not want to have to remove the ektar from its present board before I knew the size of the board I needed.
Thanks again
