This is the pocket base with the little dugouts. See here: http://regalvise.com/index.php/Accessories.php. Not new, but no issues. $100 shipped by Priority Insured Flat Rate + Delivery Confirmation. PayPal OK.
Sorry, not interested in a trade. I have been using this base on a different brand neck and head. I’m now using the C-clamp of the same brand, so no longer need this Regal base.
But thanks for asking. Email me at com.gmail@splitcane (reverse) and maybe we can work something out.
