I have seen one of these Harmony electrics in Adelaide Australia, garish green colour, been sitting there in the shop for years.
Still there now...
Nice to play, but the guy wants $3500 for it, dreamin...
I have a 1960 Harmony Sovereign Jumbo acoustic, made in the U.S.A, picked it up for $350.

Pretty nice sound, 50 year old stable timber, considering the selection of timbers used.
Brazillian Rosewood fretboard, solid 1 piece Honduran Mahogany back, I don't see these timbers at this price and age very often.
Not bad for Sears and Roebuck anyway, better than some of the later "Fender", "Airline" and "Vega" cheesy versions getting around.
Sounds pretty good for a ladder-braced guitar, in excellent condition too.
I did see a video of a H1260 being pulled to pieces and reworked as an "X" brace guitar, then played on youtube.
Lot of work, but the guy got a major improvement in tone from the exercise.
I have seen pics of Pete Townsend and Jimmy Page using this H1260 model guitar.
Here's a Harmony database site with a serial and model number search tool:

Very useful for those trying to work out what Harmony they have come across.
Good luck.
