The font below/attached is a N number on a Piper Warrior II. It will be slanted left and right for both sides of the airplane. We have used this font before but I can't find it in my system and the file had been converted to curves. I have fonts similar but the number 1 is throwing it all off. It is being used as a paint mask for an airplane being repainted so close won't cut it. Thank you in advance! 

 

Seems to be a variation of Arial (the 1 is the sticking point), but so far no luck finding it.

As Kevin said.

The closest I can find, especially regarding the relative width of numbers and letters, is Arial Monospaced.

Thank you. I did end up using an Arial font (don't remember exactly which) and hand drew the 1. Just wish I knew where that 1 came from to see if any of the other numbers are unique as well.
