Earliest 41CX serial number - olivil - 04-16-2023 03:18 AM
Hello! Looking at the earliest SN list, I noticed the earliest recorded SN for a 41CX is 2330, however my CX has serial number 2327S…
Is the list out of date or do I have one of the earliest CX?
Since this early unit was already in production in Singapore, were they ever made in the USA?
Share your early SN!
EDIT: Well that was quick, I just figured out my back shell is from a 41CV, as the label does not mention the ED shortcuts.
