I just found this incredible video about the history of the Merwin & Hulbert Revolvers made by the Rock Island Auction Company! I can only say ''WOW!''
Thanks for sharing this guys!
This nice Merwin & Hulbert single action revolver with Ivory grips and the skull crusher grip was for sale on Antique Handguns Marketplace (AntiqueGunsCollectors.com), but unfortunately it was sold a little while back.
