Hi paulj.
I have not seen any of the labor leaders daggers at all change hands, let alone a Puma with the Puma chain. So, I can not give you an answer.
The Bulgarian army with hanger can trade for $1,500 to my belief, but I was recently contacted by a legitimate collector who thought his was worth about $3,000. I think Johnson has quite a few of these at a good price. They are undervalued.
Just my opinion
