I have a Complete 6 lobe Emory Crankfire that I purchased along with a gun last year. Unit is complete with instructions. I have never mounted the unit on the gun. I cant say if the owner prior to me used it.
$500.00 plus 9.00 USPS Priority with Delivery Confirmation
Going to offer it up to a 1919 member before gunbroker. The last two sold on there have gone for 575+.
