In my opinion Ballak drew the line between 30 and 31 wrong. This is based on observing the casting date on cases and correlating them with serial numbers. I don't think the 31 model year started until at least 36000, maybe not until 36200 ... Perry

It seems that an inordinate amount of 1931 KJs still exist.

There seem to be a lot of 1929's, and a lot of 1931's out there, but not too many 1930's.

Could Ballak's serial number list be wrong? They show

1929 - s/n 28000 (between 4000 and 5000 bikes)
1930 - s/n 33000 (between 1000 and 2000 bikes)
1931 - s/n 35000 (unknown when they stopped, but the highest serial number I've seen is 36862)

Does anyone have a bike with serial number 35xxx or 36xxx that has a title that says 1930?

It just seems odd that so few 1930's have survived.
