I just purchased what looks like 2 new in the box international 50s and would like to know the year they were made.
The serial numbers are ND4348 and LD2614
Thanks Jim

Interesting, these don't seem to follow the old original serial# date code, or the newer [current] code.
Using the old code, they "might" have been built in 1994 and 1992, respectively, but I am pretty sure the new code was already in use by then.
Are they "50S" models [2-speeds], which came out in 1987, or just "50" [single speed] models, which came out in around 1967.
