We actually do quite a few paint masks and decals for these old planes. I
made a set of Numbers/letters up for my own use and a nice man on the
letterhead board created a font from it and called it Warbird Classic. I gave
it to him and I think he has it on his site for free.
but I don't remember
the site. The kerning was never set (easy to do- distance between
characters is the stroke width) but it looks a lot better than the USAF
stencil-which is too tall. Email me if you want a copy. Gene
