Hi,
Don't know if this would work for you, but I still have a Sinar 8x10P (the first model) in good user shape. Also not familiar with the "Special Front Bearer" you mention, but this was built as an 8x10 (not adapted up from 4x5), so I think the front standard has all the movement capabilities you could need.
If you're interested, PM back & I can send pics, get more specific with details, etc.
(oh yes, you may be able to tell, I am in USA)
