Fooled around with the lettering, numbering. Interesting that the number 1 isn't the number character but is the letter "i" in lower case.
I'll also try changing the size of the lettering to about half it's size as shown to make it a little more subtle. May also try different colors in the lettering (this one is black) depending on the wood color. The fellow who does the engraving is a very talented sign maker, so we'll put our heads together to see where we can take it.
