congrats on the barber , I found the same valve stem cover for a model tee,that was made between 1907 to 1915, made brass and nickel. you have a great ,awesome and neat find. keep it up
42-44. Being the first Barb I found it was jumping from 24-46, must have been how it was laying, when I air tested a 46. Quarters have a higher tone, really squawks at you, a good squawk though.
John D, I could not figure out what it was, seen a post of someone else with a valve cover stem they found, and this is threaded, just thought it was big for that...thanks for the info.
