You're really good at this, shaggy!
Here's the F15 Shield I made. Not really appropriate for the AJS 37 since this shield was used during the AJ period, and earlier. Not commonly used on the Viggen either. But I like it! ;)
Now that I have traced the crown, the rest of the Wings shields shouldn't be a problem...
I have left out some highlights, and shadows, in order to keep it "clean". Maybe I should add them..?
