Please identify this font for me. I'm restoring the old bike.

So you are joining the MZ owners hitchhiking club… excellent.
Unless there is a 'revival/recreation' that has been done that I'm unaware of I doubt you'll fin this as a font. Decals and stencil templates available:

Thanks. I know the decals are available, but i need to find the font to make custom stencil, not with the Trophy on it, but with something else writen in this font.
