Info on 5x7 Curtis Color Camera for Tri-Color Separation

Curtis Color Camera for Tri-Color Separation-- Any info on this--Is it worth anything as originally intended or just as a 5x7 View camera--I have none of the filters--just the camera---only difference from a VC I see basically is that the 5x7 GG assembly slides after focus and a film holder is slid back into that position--typical VC spring back.
Any info ??

I have the, what looks like 2 1/4 x 3 1/4, color filter set in a box, Red, Green, and Blue filters on glass in film holders by Curtis Camera Co. for a Curtis Camera of somekind but never got the camera.
