And now found the answer to my problem:-
On the back of your iPad look for:-
iPad 2 (Wi-Fi Only)
A1395
iPad 2 (Wi-Fi/GSM)
A1396
iPad 2 (Wi-Fi/CDMA)
A1397
iPad 3 (Wi-Fi Only)
A1416
iPad 3 (Wi-Fi/GSM AT&T)*
A1430
iPad 3 (Wi-Fi/CDMA Verizon)
A1403
Sorted!!
I can now look at a group of iPads and see which generation etc they are without turning them on or having to compare with another.
