It's the model 214, back set. That was the first of the series. I now only have one early Accutron left in my collection and it's the 214. I was looking at a used Bulova Precisionist 262 kHz at the pawn shop last weekend. I didn't get it, but it was priced at what I saw others like it selling on Ebay, but next month they'll lower the price even more, so maybe I'll pick it up then if its still available.
