I'm sure one of this site's 'elders' will take a stab at it.I guess that's me. I'm an elder. As I recall, George Martin (Jim Lansing's brother) was in charge of keeping track of serial numbers (on Fletcher Drive, and on Casitas Avenue).

The cone is super clean - front and back - and there's no glue drips I can see. There are some numbers stamped on the back of the cone, but that's it. Is there a way to identify a re-cone from an original? Also, I don't know how old it is. It's serial number 47352, if anyone knows how to read a JBL serial number. Thanks for the advise.

He entered all the serial numbers he had used each day in a small book he kept at his workbench. I believe that book got destroyed in a fire.

That was the only record of which serial number was used - and when. The only other possible source might be the nameplate company (was it Nelson Nameplate?) who might still have some records as to serial number batches they made during a period. I think we ordered about 3 or 4 months worth at a time.

Hello all, I have a JBL E120 8 ohm speaker that I have had for about a year or so. It came to me in a trade with some other gear and I've really enjoyed it. It's clean as a whistle and sounds fantastic. I really don't need it and am thinking about selling it.

Also, I don't know how old it is. It's serial number 47352, if anyone knows how to read a JBL serial number. Thanks for the advise. Thanks for the response. So, there is a small white ink stamp on the back side of the cone, it's a number: 61827, I believe. (It's a bit smudged).

It also has 'T46' stamped under the number. There's also a place on the backside of the cone where someone wrote in white grease pencil 'E120-8'. It had to have been written with the cone removed because the basket would have prevented anyone from writing it with the cone installed. The cone is absolutely immaculate - no dirt, dust, dents, etc., which makes me wonder whether or not it was re-coned in the last couple of years. Thanks again.
