Linhof back for attaching H back to view camera

[pchong]

One of the older Hassie catalogs featured a mounting solution for the H back to ta view camera with a long back plate attached to the rear standard of the view camera, which contains a place to attach the H viewfinder (90deg or straight), back and battery to power the back. It seems to me that because of the battery attachment, you can shoot directly to the CF card or tethered without additional power for teh back...correct? Anyone knows if this was ever made, or if still available? What is the Linhof part number? Thanks.
