My FP has plate number 261235 and serial F9935356, indicating that it may have been sold as a 2000 model year. You have F9935381 in used sold with 261339. You have three 15th where I can make out the plate: 263395, 263649, 263743. So I have a tendency to think that these are more of less sequential.
Are you sure about this one? 263395
Since they only made 125 for the US as a special run the spread of 400 numbers doesn't jive even if a few other countries jumped in also [Canada, UK did]
Even if they are sequential they generally make little sense.
So there was a batch of 06, 16, 25, 26 with no rhyme as to why the 0, 1, 2, or the 6, 5, 6. The last 4 being sequential I could buy but doesn't explain the prefix. I dropped the ball on the JEM plate number oddities and concentrated of JS
plate numbers trying to narrow down the graphic ranges, JPM serial number to find the 100A range, I knew the JEM oddities existed but never made a real effort to track them, and with no real way to date them anyway except for those with headstock serials like FP15TH's would be fairly futile anyway. Aside from a couple PMC's with 92' plates I don't know of any others, though I'm sure there were but on models I was not following. I've never seen a 93' plate, doesn't mean they don't exist, but IMO sometime in 92' when it was decided the AANJ would be used on future JEM models [EVO and the proto VWH's were 92's] I believe that's where the dated plates stopped and these oddball numbers start.
