You can read about both lens in this Kodak Lens Catalog: http://www.cameraeccentric.com/html/info/kodak_4.html
The elements may physically interchange but optically they will not.
Have the slow running shutter(s) serviced as they will die if you do not. I recently CLAed a Supermatic that had been used until it no longer functioned. It cleaned and adjusted with 2/3 of the speeds correct (in tolerance) and B&T functions marginal.
1 inch=25.4mm; 203/25.4=7.9921259842519685039370078740157 called 8 inch for convince. You need 8 inches of bellows draw to focus it at infinity, approximately 9 inches of bellows draw to focus at 10 feet. 127/25.4=5. You need 5 inches of bellows draw to focus this lens at infinity, approximately 6 inches of bellows draw to focus to roughly 4 feet.
If the lens board is large enough for the shutter to fit on and there is enough bellows draw to focus it at the distances you plan to use it for then it will work on that camera.
Use the private message function to inquire about my servicing the shutter(s) if interested.
