Need help identifying PICAXE 28

I have about 15 PICAXE 28 (some 28, some 28A and some 28 X). I kept them in separate containers but my wife decided to HELP me to keep a neat work bench and "consolidated" the storage bins.
Is there a way I can find out the type of each chip?

Hook them up to the download circuit and use "Firmware?" button in options of programming editor.
