Bill;
Now I feel like the boy who cried wolf!
I was actually serious about the potential serial number;
I did not know Zephyrs were not numbered.
The sticker on this one looks like it has been there since day 1,
but now I'm assuming it was added later by some operator with a large number of machines to keep track of.
About 1/3 of the sticker is gone, but it does not look like there was anything printed on it except the number 000903.
