Spice question

[dmh]

I've just weighed all my Spice models to work out which are solderless without opening them and I get different results to those below although the difference is about the same. I weighed without batteries or case (with battery cover).

Are the measurements below without batteries or case and with battery cover?

I checked my scales by weighing my mobile phone and it exactly matches the vendor specifications and is within the same range so I believe the scales are accurate.

To partially answer the question about what year... I don't have too many Spice machines, only 1 of each (except several 34C, because, well... they're 34C's) but these samples partially clarify the changeover date:

HP-32E: 2134S, 217g
HP-37E: 2219S, 174g

Thanks to Steve for the simple weight metric, very handy.
