10" Parks mirror cell for a full thickness mirror. $100 plus $20 postage (it's heavy cast iron!)
If you don't understand the term "full thickness" this means it will take a mirror about an inch thick, as in the old days mirrors were made to a ratio of of 1:8 i.e. a thickness of 1 for every 8 in width. So if you have a modern "thin" mirror you might need to put some "padding" under it.
I bought it for a project that never came to fruition. The cell is in excellent condition, bought it off another Ice in Space member many moons ago. I use an 8" model in my personal dob and have had no complaints about it over the years since 1997.
PM me if interested.
