Nice buy Keith, that's a really nice kit overall, and as Evan said, more accurate than the Revell kit, although the latter has more internal detail, most of which can't be seen.
Jan, e-mail me a good shot of the nose art for the B26, and I'll see if I can make the decals at the same time as the B25 ones. I can do the '13' for the tail, but I'll have to figure a way of getting the white outline - probaly do a very fine Olive drab outline around the white, and print onto white decal paper - should disappear once on the model.
Mag, the decals with the Marauder kit are for a 9th Air Force B26 based in England,, and a French aircraft, neither of which were in the MTO. However, I have seen MTO decals advertised, but can't remember the manufacturer! Maybe Jan can help?
