I'm fairly certain only 3 of these were ever made.
I saw one of these cans on Ebay while searching for cans to make tube calls.
When I saw it I instantly thought ''2 in 1 tube call''.
I ended up making 3 of these ''Double Barrel'' tube calls - 2 hens in one call
It has a divider down the center of the can, it was used in WW2 as an oil can for guns,
Took a LONG TIME to clean them out but they work!
