The mount and finder are Edumnd. The mirror cell and spider are Novak. I have the exact same mirror cell and I'm building a 6" f/20 Dall Kirkham with it.
The primary is made from an old style Corning "Slope Sided" Pyrex blank which was popular in the 50's thru the 70's. The owner's name in the back and was most likely inscriped when it was coated. The optics are most likely a Dall Kirkham configuration and could have been made by Coulter or 3B Optical. You need the exact radius on the primary and that of the secondary to calculate the spacing needed for the secondary to secondary distance. You'll also need a baffle tube in the primary or the image will be washed out from sky light.

wow. that was how mine came. The Edmunds mount with a 6" cassegrain riding on top. Just because the mount says Edmund does not make the optics Edmund. Edmund sold a lot of mounts.
