My truck is my signature line below. If it has a VIN of CM20DBA10001, would that mean it is 1) the first 1969 vehicle out of the Baltimore plant 2) The first truck from there 3) the first GMC from there 4) the first GMC V6 3/4 ton Wideside... well you get the idea. What would initiate a run of sequence numbers?

Now if that were known and if one knew the production rate that the sequence applied to and the date of the start of production of that sequence, could the approximate build date be determined?
