i was just wondering of anyone out there does replacement decals for the US M113's that were supplied to the Iraqi army?

Most of what I see are Iraqi national flags on the sides, with no standard size. If there are numbers on the front or back you can use generic Arabic numerals.

For the flags, try this:

I've had trouble finishing my Iraqi HMMWV because I could not find the correct flags from existing kits. What they did in real life is use vinyl stickers of the old flag, and paint the stars out with white paint. Problem was the Takbir as not correct for the current flag. I might even help you offset the cost by taking a few off your hands...

This is a subject that I wish the aftermarket decal companies do a sheet on,Post Saddam Iraqi armour.

Jason, et al.,
Well, if you have references or know of sources, I might be able to put something together. Or, at the very least, I could do a custom sheet for you. Drop me a PM if interested.
