Silver border CV - orignal?

[TallKey]

If SN is *A0* it is a C.

If it has a silver border, then it is a C.

I recall border and chin logo being gold = CV or CX

Recently acquired the 41. Have read enough on this forum to wonder about it being a factory transition model or an HP repair mash-up.

So it started life as a C. Thanks all for the above data.

Need a spreadsheet to track the variations and have started one but it looks sparse.
