Model 13 anomaly?

I have a model 13-1, S/N 3D15XXX that I bought new in 1974 or 1975.
Page 399 of the SCOS&W shows that model 13's produced begining in 1968,
going through 1977, are numbered in the range D1 through D999999, consecutively.
Next, for model 13, is shown two ranges for those produced 1977 and 1978 with 2D prefixes. Then 1979 shows 4D through 6D prefixes. There are no 3D prefixes shown.
or leastways that I can find.
Has anyone run into this before?
Thanks,
teesur

Some model 10-6 frames were over stamped 13-1 by the factory.

You might have one of those, though I thought the over stamped frames were in the 6D or 7D serial prefix. Only way to know for sure is to letter yours. Regards 18DAI.
