With some great luck, sharp eyes, lots of help from Audio Fan(who found and saved these) and Gordon(who drove over 2000 miles to make sure they made it to St. Louis,) I now have a pair of 1957 Harlans to restore and treasure. They spent at least the last decade or two in a back forty shed on a Carolina property, stuffed with a 12" University woofer and a horrid gold University tweeter in one speaker, and a 12" EV whizzer cone in the other, along with a squirrel or rat nest. This selection of speakers is mystifying to say the least, as the Harlans were a very design cutting edge speaker from JBL's early days. How they went from a probable university professor or engineer's MCM home to an audio collector's outback country estate would be an interesting story in itself. I had a big stroke of luck with the veneer. Even though the veneer has started pulling off the plywood on both speakers, it is readily identifiable as mahogany. Also, the warranty card packet that survived stapled to one speaker back had C39-M written in pencil. This means the speaker was sold as an empty cabinet, and had mahogany veneer, providing confirmation for our assessment. We will need to pull all the veneer, and replace it with some mahogany species. I am inclined to put ribbon sapele on, as it would be a knockout for grain pattern. Jbl always installed the veneer on Harlans so the grain ran to the front leading edge.
