Can anyone point me to where/what style font I can use to make N numbers in the military/block style for my civilian airplane?
This style used to be printed on the back of trim monokote sheets.
Thank You in advance

You should find something that suits your needs there

There ared so many fonts already in Microsoft Word that I would expect you could find one you like. Just experiment.

I think this is just what you are looking for the
AMARILLO USAF font.

Falcon 56...BINGO. Thank you. It is exactly what I was looking for.

If you want numbers and lettering in the US WWII style, try USAAF Stencil. I found it for free on the internet.
