Serial number lookup


I am looking at buying a JCM900 4100. its serial number starts with M-2001-49-0xxx-B

i recall someplace typing in the serial number for my DSL and it decoding it to the correct model. i can't find that anymore. Thought it was on this site.

how can i look up this 900 SN to see if its legit?
