I am not aware of it (or even the article you mention), but if his survey information does exist somewhere, I would certainly like to compare it to my own survey covering the same serial number range and timeframe. Currently, I have 10,509 serial numbers in my survey for the years 1932 – 1955. My research survey actually covers the years 1907 – 1963, and it currently has 17,844 Model 55, 64, & 94s in it At my current pace, I am adding 6.5 new serial numbers per day, and should be well over 19,400 by the end of this year. I truly appreciate all of the assistance received from many of the WACA members thus far.
