Hi Blu, Jack and DeeJay,
I might be a year and a couple of months out but that twin ID plate is certainly only on the very late single decks (from memory) and early twin railers (certainty). I too have seen a few "Craftsman's" on eBay from time to time, this is definitely a certainty. Again I feel that the later version Kirby is a ring in as it is too plasticised as they were still using the orange all metal units right up to and including the early twin railers (see photo below)

notice the twin ID plates on this one. So that most definitely says that the plastic Kirby is a ring in.
What's the thoughts ?
Cheers,
BB
