USMC stencils

thanks, that's good to know, I guess I will use the Archer set then

Not really.  It is hard to get a lighter color (red/yellow) to appear on a darker color like OD Green.  Home printers don't lay down a lot of color and the decals appear almost transparent.  To get them to show well, you still have to use the white backing paper.

it's my understanding that the Marines also stenciled in Reg. numbers in yellow, which would solve that problem.

I am assuming you are talking about white stencils on WWII vehicles.  I don't know how much experience you have with making your own decals, but unless you have an Alps printer, you can't make white stencils easily.  A normal home printer doesn't print white since the paper is white.  To make white, you have to use white decal paper and surround the stenciling with a square the same color as your vehicle color.  That is the hard part, matching the vehicle color.  This is the reason Archer and other AM decals are so popular.

thanks, one or two of those might work

I'm sorry if there's been some confusion, but I'm looking for a computer font that is similar to USMC stencils, so I can do them myself.

The Archers look good and are inexpensive. You can get them directly from Acrher.

that's cool, but I wanted to try printing them myself for this one.

Archer Fine Transfers has WW2 Marine Sherman sets. Go to their US armor complete sets (dry or waterslide) and the first two listed are Marine tanks. http://www.archertransfers.com/
