No stamping error here. The gun is stamped 16. All the stamps are as I would expect to see on an original, unchanged Ithaca.
My friend and highly regarded member of the sales and trading team at this shop measured them. They measured as a 14 gauge would.
I can see absolutely no evidence of any reamer, hone or tool in the bores or chambers.
Best,
John
