41CX serial #'s -- halfnut/fullnut


A current eBay auction offers Two 41CX calc's. The displays indicate that one is a fullnut, and the other is a halfnut. The serial numbers given are 2503S41819 and 2617S20215. Obviously, the latter must be the halfnut, since the changeover occurred during 1985.

The MoHPC indicates that the first halfnut 41CV found has a serial # 2511S... (assuming this is not a factory-repaired unit with new innards).

Does anyone have a later halfnut 41CX?

I assume you mean a later fullnut, or an earlier halfnut;-)

I have a fullnut CX w/serial #2506S42734 .
