I have for sale a 6” F/4 Mirror. I’ve had this mirror for years, always wanting to build a scope out of it, but it hasn’t happened by now and I don’t think it ever will…
This is an old mirror, ground on a cast Pyrex blank with the tapered side that you just don’t see any more. On the back of the mirror are engravings that say: “Refigured by Cave Optical, FL 23 5/8” F/4, #1301”. After checking the Cave Mirror Registry this serial number would put the time of this work done before February 1959.
The coating on the mirror is Beral done by P.A. Clausing. The coating is in fairly good condition but does have some pin holes from corrosion and hairlines scratches. Overall though it still is bright and reflective not needing recoating any time soon.

Asking $195 which as always, includes the shipping and PayPal fee. Now $140

Clear Skies,

Paul
