I'm confused about how the serial numbers run on the J's. I own a 77' J with a serial number of 24-0109. I see some 77's with serial numbers that are like 24-1035.

How can this be? They couldn't produce that many J's in one year.

Serial numbers are always serial... except when...

 

1) There were two changes at factory...

First, All the planes just got a number, it wasn't separated by what model it was...

My '65 C got a four digit number...

Second, in 66, all the serial numbers started with the year they were built.

Third, Somewhere near the 70's, each model line was represented by a number.  So Js all start with a 24-xxxx

 

3)  Where things become unhinged...  the first J started out as one of the last Fs.  Development took a few months...  when it got it's new serial number, it didn't fall in line very well with all the other Js....

 

Now I'm going to read what Rich just posted above... (nice link, Rich!) :)

When building machines, it is incredibly helpful when the serial number actually represents all the technical detail that went into the machine.  A second level of being helpful, is when a mechanic knows what he is working on just by the serial number...

All these numbers help the owner to know what he has, and get exactly what he needs when ordering parts and service...

Best regards,
