Figure it out, I was wrong on the name. I forgot Pappy Gunn was famous for terrorizing the supply chain and flew a B-25 named "Not in Stock"
Lucked out and found a picture of the plane though not the best. Note the way the K is formed and the quotes. Funny thing is its actually the opposite side of the plane as well.
A nice find Paul. I have enlarged the name a little bit and it seems to be of a little bit different shape. Contrary to the port side letters the starboard ones look like being of the 3D form.
Thanks my friend. Considering most painting done by hand I think this will be the closed I find to being the ship without finding the other side in same size.
