Finding a Model 11 is hard enough BUT TO FIND ONE WITH WURTZ IS LIKE LOOKING FOR NEEDLE IN A HAYSTACK.
I have a CUSTOM One-Off Based on a 1965 Catalog Model 11. Some people call it a HYBRID others a SPECIAL ORDER CUE.
Either way I believe it's one only one in the KNOWN UNIVERSE.
It's been refinished sometime ago. I bought it from a collector 7-8 years ago. It's a collectors piece. $2K.
I can send you photo to your cell phone if interested.
