Serial Numbers
LOL. I have a decoding chart, and the info can also be found online.
First letter is manufacturing facility. C = Clyde OH.
(There may be an extra leading letter for "foreign"/3rd-party manufacture such as the Duets made in Germany.)
2nd character is year. L = 2001
Prior to 1990 the coding was 0 through 9 per the last digit, i.e. 0 = 1970, 9 = 1979. Letters were added in 1990 to reduce repetition of the pattern.
3rd & 4th position (numbers) is the week of the designated year.
Remainder of the number is production sequence in that week.
Being that there is repetition in the coding, it's sometimes necessary to get a visual on the machine or also reference the model number to differentiate, for example, 1970 from 1980.
