If it is a 6500 series, there were:
- around 4800 made in 1950 (1% of trucks produced) and
- around 9000 made in 1952 (3% of trucks produced) and
- around 8400 made in 1953 (3% of trucks produced).

Those number are supposedly for calendar year, not for model year.

I have not seen any other Advance-Design year's production numbers.
