I picked up (some) of a Toyo 45G on e-bay (of course) which arrived last week. I'm a bit confused though with regard to the back. I think some of it is missing.

There was no ground glass with mine and while I can find cheap (crap?) ones on e-bay I'm not entirely sure how it would even attach. Mine is the 360 degree revolving back.

This is a photo taken by the seller: http://i22.ebayimg.com/06/i/001/1d/93/1b16_3.JPG

Here is one from a different one for comparison: http://img.photobucket.com/albums/v2...hot_03_124.jpg

The manual shows the 'focussing frame release' (wording from the manual) but it doesn't appear on mine (reasonably clear when the two images above are compared).

Am I missing a crucial piece? Having reviewed 'Using the View Camera' it seems most likely, as if I could attach a film holder, I'd still need the ground glass removed (as it'd be on the wrong side of the holder (i.e. between the film and the lens).

If I am missing a piece, do you know what it is called and if I'm likely to be able to get it? I've been searching for information today but to no avail. I've only seen full revolving back 'kits' (which ambiguous pictures showing only the back of the piece I have) which cost far more than the camera.
