Need help on Graphic No.1 Kodak Supermatic Shutter
I have bought a Wollensak 3 1/2 in F12.5 with Graphic No.1 Kodak Supermatic Shutter for my 4X5 camera. But the low speeds (speed mark in RED) did not work while the fast speeds (speed mark in BLACK) worked normally. When I tried to open it for maintenance, I failed. After I re-install the spring back , the shutter doesn't work.
Does anyone have the service/Repair manual of this shutter? I have not have any detail information about that.
Anyone who has, please inform me by email: email@example.com, Thank you very much!s
