I'm sure 07ms (if thats the one used in the Barco 80* and Sony 12** series)is physically bigger than sd-187 and so wouldn't fit in the 7 series. I beleive SD-187 you find in the earlier smaller analogue control Barco models (like the 400 and 600) the Electrohome ECP 3*** and 4*** series and the Sony 10** series. Hope this helps.
The tube width and mounting points etc are definately the same. I think if there is an issue it may be that the length is different - I can't remember... If it is, it's by a cm or something, so hopefully not a problem.
