I just heard back from the good folks at the Drum Center of Portsmouth.
I had asked earlier if they could inquire with Hoshino the following:
Is the Repro-Badge the original size? Baked enamel on Brass?
NOS or currently being made?
Hoshino replied: "Original size? – If not perfect, should be extremely close. Not real baked on enamel; the lettering is embossed and the white area is printed. The badge is brass material. We are currently making these now, they are not NOS".
Has anybody here had a chance to compare these in person?
