Frame number CH0XXXXXXX
About the frame number (from vintagemongoose.com)
Each frame had a combination of three key numbers or letters. For example:
CH8 123456
Again, the C stands for Cromoly to make note of which frames were updated with Cromoly. The very early frames were mild steel.
The next letter in the sequence is the month code.
A = January
B = February
C = March
The next number is the last number of the year the frame was produced.
6 = 1976
7 = 1977
8 = 1978
9 = 1979
0 = 1980
1 = 1981
The rest of the serial numbers are sequential and are the number of frames produced in that series.
