GP FRAME NUMBERS

[wurzel]

Does anyone know where I can get a set of original size frame stamps ?
I've got a GP that used to have really clear numbers,but after a few blasts and
re-paints the numbers have become pretty faint and although you can see them
really clearly when blasted, the last time it was painted they all but disappeared.
I am due to repaint the frame and want to re-stamp some depth back into
them as I would like them to be easily made out.
I don't want to mask and clear coat them and I also don't want to try and engrave
them as they will end up looking like they've been tampered with.

Cheers in advance Mark
