I did some quick calculations on those numbers and arrived at a ball park figure of 4,700 units being produced each month. Given static production rates (which is a little unlikely, but helpful none the less) the following date of sale/serial correlations can be reached:
15/8/1956 - #34,252
15/7/1956 - #29,552
15/6/1956 - #24,852
15/5/1956 - #20,152
15/4/1956 - #15,452
15/3/1956 - #10,752
15/2/1956 - #6,052
15/1/1956 - #1,352
6/1/1956 - #0001
Allowing a generous %20 margin of error to accommodate fluctuations in monthly production rates, arrives at a +/- 6,800 units, suggesting a date range for the first Model 2 sold to be between the start of December, 1955 and the end of February, 1956. In reality, it's probably much closer to a January start date, but this 3 month window gives us something solid to base any further research on.
