Thanks Sonic, that was quick.
The first one with solid black lettering will work best, it'll be going on a chrome-like background. Thinking I might try to rotate the B clockwise so its back is the same angle as the side where the two screws will be.
Now I need to find a sign place to print up a few. Is this a common font they will recognise or should I give them that as well?
Thanks again, really appreciated.
