I recently acquired a number of antique Hemp boat Fenders. They were branded Penn Yan Boat Company. They were new old stock, but many had deteriorated in storage. These snap hooks were salvaged from the fenders.
Price is per ONE piece.
They still smell like pine tar and hemp.
These look to be cast iron with galvanized plating.
Lots of patina
Working springs
I think these could be from the 1920's, give or take.
