I believe only in the earliest ofthe explorer dial 5513’s. I could be wrong. But pretty certain the all red depth era 6538 explorer dials had the numeral depressions. That’s one of the reasons I never pursued a build like that; having a gilt Dial made in such a fashion wasn’t economically prudent.
Keep in mind that the 3-6-9 dials had the brass plate “carved” out I believe, to hold the luminous rather than just being applied to the plate on top of the lacquer. If you want it done right, that’s the way to go.
Never thought there'd be so much excitement over spring bars. Lol The bars come in packs of 10, so my suggestion would be to place orders in those increments so@sputim doesn't need to repackage. Anyhow good luck boys.
