"The highest Model A 250 serial number I've ever seen was in the mid-12,000 range of numbers". Hmm, my own A250 is numbered 12080, so I guess it is later in production than I thought. Either that or it is the one that Ron is talking about since he's been to my house a few times. There is another difference int he A-250 that I haven't found in the others. The lock mechanism takes a key that has only one notch cut into the 'tooth', not two as in all other DDs I have had or seen. I have a Dolphin key that has the one notch cut in it as the other will not fit. John Robles
