Double Tumbler by Jon Keegan

Had a lot of fun solving this one!  Kept me busy for sure.  This is a used tumbler in GREAT condition.  You might find some very minor machining scratches, but nothing that will throw you off.

Please wait to send payment until shipping has been calculated - F&F appreciated, but not needed.  Thank you!
