Inquiry about Greenhoe serial numbers.

[tromboninator4000]

I've recently acquired a Greenhoe Edwards Bass valve section that the seller purchased from Gary at ITF may of 2002. I've been looking all over for a serial number but the only markings I could find is 47 in the F trigger saddle. Just wanted to see if anyone could confirm if that is indeed my SN. I will be sure to contact Greenhoe. Any help is greatly appreciated! Thanks in advance.
