Need help finding a shutter for a Seneca 8x10 Rapid Rectilinear Lens

[ataim]

Well, I know what kind it is, but the guts from the shutter and aperture are missing.
Information on Lens:

On barrel of front element:
Seneca Camera MFG CO
8x10 Rapid Rectilinear

On Shutter:
Wollensak Optical Company
Rochester NY
Chrome Piece is 8 - 256 (by my thumb)



First is lens worth fixing and getting this lens back into working condition? And Second I cannot find out information on which shutter to use. Any help is much appreciated.

Unscrew the front and back lens cells and measure the threads. Then you can compare with tables for which Wollensak shutter might fit. It looks like it could be a Wollensak Regno shutter. You can find the old Wollensak catalogs on cameraeccentric.com

You may already have this information concerning the U.S. System (aperture scale) on your lens, but here is a link which is very informative:
