Choke in Left tube and none in the right... The lack of the "choke" mark doesn't mean that it's cylinder. Just means there's not a lot. Could be as much as .008 constriction. And can narrow the date just a bit more than 1904-25. It's a Birmingham proof but there's no date code marked. That was introduced in 1921. So 04-21. Last edited by L. Brown; 11/05/19 08:28 AM.
