[Elecraft] K2/10 serial number 100

[K9SW]

I recently bought a K2/10 and realized that the serial number is 100, which is a low number.  I recall reading that Eric and Wayne initially sent out 100 kits to beta testers so they could get their feedback on the building experience and the rig.  

Did those kits have serial numbers, and does the serial number 100 mean that this K2 could be one of the beta tester kits?
