Sinar Shutter on Horseman 450 EMII

I bought a Sinar Copal shutter believing it would go on my Horseman 450 EMII, but it doesn't appear this will be the case, unless I'm doing something stupid. Can anyone advise if this shutter should go on this camera. I appear the knobs and levers on the side of the shutter hit up against the L Frame, and the top sliding holder wont go down because the shutter does not fit neatly.

Any advice on this would be welcome.

Regards

Colin

Quick fix is to turn the L frame through 180 degrees. Having said that I use the shutter on a standard Horseman 450 - it seem to work OK as normal.
