Need help with Toyo Metal Field 4 3/4" x 6 1/2" Sakai Special Accessories

[helios1014]

So I have a Toyo Metal Field 4 3/4" x 6 1/2" Sakai Special camera. Can the backs and accessories from other Toyo models or graflex cameras be used on it?

Edit: please note, I do have a 4x5 back for it already.

The back fitting for this camera is unique. I assume you have the regular half plate back and a reducing frame with a 4x5 back. Other backs (5x7, 8x10) from the G series will not fit, nor are there any adapters. There is an adapter for whole plate, which has a bellows. The half plate and whole plate film holders are also unique - they are thinner and narrower than other makes. Do note that one quite rare version of this camera accepts a 5x7 back from the G series.
The camera accepts Speed Graphic lens boards.
