26 kc_eddie_b 11 months ago Earliest electrotone 6119 - #406xx (one owned by GDPer) There's a 6119 that predates the 6113? I was hoping nobody would catch that Afire... but since you have....The history of the electrotone Tenny remains frustratingly unclear. The last batch of the F-hole, red finish, single filtertron was #406xx. I have documented specimens displaying those 1st generation features at #40669, 40672, 40678, and 40679. BUT... then there's #40680 which has all the 1962 electrotone Tenny features. I've only documented one other at the end of that batch #40697, and it too has those '62 features, so plausibly the last 20 guitars in that #406xx batch are of that new design. Then, at batch #415xx we see the introduction of the 6113, and it's electrotone feature set. Another group of these (non-Chet) Tenny's occur at #419xx, and then a smaller group at #421xx. The last of these occur in the early portion of #426xx. The next oddity happens later in that batch when a few Tenny's with '63 style (faux binding) f-holes emerge, fretboard binding, and standby switch. When the next batch surfaced at #442xx, the '62 Tenny features (unbound f-holes) are in place, along with pot codes from Feb of 1962.I've been hoping to find additional 6113/6119 specimens to help fill in the data, and hopefully verify the info I already have, but progress is slow as all I can do is wait for more Tenny's to surface. I'm feeling the pressure to work all this out before releasing a 1960s book.
