Zeiss ZM Seicail Edition question

[clicker]

Hi,
Just wondering if all chrome ZM's are marked special edition on the top plate, and if not any idea how many were marked in that manner ?
Thanks

My SE is marked on the top plate and I think there were either 999 or 1000. There is a regular serial number and the SE number also. Mine is 6XX.

I believe the initial run of "Special Edition" cameras was 1,200.
