I did a quick search for "Yamaha CS15 SN" on the site to see what other serial numbers came up. They are all four digits and none were earlier than 1001. Unless there's a 1000 out there or they started with 0001, this is likely the first production CS15. Curious if it went to anyone special when it was first release or if it was simply shipped out with the first units.

"Overall, the synth is in excellent working condition. The front panel is very clean, with only minor blemishes. The side panels are nice and tidy with minor marks. The rear panel is also clean with only minor marks and blemishes.

All knobs, buttons and switches are present, original and function correctly.

All keys are clean and aligned and contact correctly.

The unit was tested today and the synth is working as it should be: 100% functional."
