This may help. If you go to www.asw15.org and register for free, then
you can download the asw logo's....not sure if that is what you want.
I did it and printed it in vinyl for my glider. worked great. You
may be able to just cut out the 15 out of the asw-15 logo...

email me at liv2soar at yahoo dot com if you want me to send that
document.
