Anyway that's just a guess.
I suspect thats whats happened the cane has been stuck in a barn or somewhere gathering rust, the threads been cleaned up to reveal whats left.
I cannot see somebody hand cutting a thread on both ends and then hand cutting the female equivalent connections.
Its bad enough trying to sort out a crossed thread on a bolt, a hand cut thread
an internal thread to fit
Just thinking about how I would go about hand cutting a thread on an 1" dia tube using a file? and a saw
I also restore Old American from the 1800, BP rifles and they have rifled barrels of all shapes and sizes.
Not wishing to bore anybody but some of the Back wood Good old Boys cut the rifling in the barrels by hand but then we are talking 1 turn every foot.
which a hell of a lot easier than cutting a 10? tpi thread on an inch dia lump of metal!
