Wish i had the rest of the scope these would go with ...
One pair of Uniclamp accessory rings for the rare-as-hen's teeth 6" Unitron refractor. I.D. is ~6.25".
These rings are in as new condition, the green felt is clean and they are undrilled (unused.)
Now, i have never seen a real-life Big Unitron, so honestly i am not sure if these are for the 5" or 6" 'scope. If you know better, please let me know. If you know Unitron, then you know how scarce anything for their larger 'scopes is.
SALE PENDING. THANK YOU!
