I also read somewhere that at the time of trying to initially sell the 757/767 to new customers the 100 series was considered unpopular as a mark by Boeing following poor sales of the 721 the most popular 737 mark at the time was also the 732.

Therefore the original production series of 757/767’s was redubbed the 200 series.

This is pretty accurate, Ren, at least according to all the readings I have done on both aircraft.
