Hi Erik

Here some pictures from a real TallKey CV.

The S/N is 2103 A 10255

This is the lowest know to exist real HP-41CV S/N.

Note: All CV’s in 1981 starts with a 1, also 10255. If you find a lower S/N which starts with a 0 then the backside comes from a HP-41C.

Actually two CV’s with TallKey are known to exist, the other machine has the S/N 10260. Both are manufactured in USA.
