Another way to check is to look at the blank area on the disc next to the label. You'll see a matrix number, something like 1423456. If it stands alone, it's acoustic. If it's preceded with a circled W it's electric. Compare any Harmony with any Columbia from the period to see--and hear--trhe difference.

The giveaway is the complete lack of deep bass. I'm sure a spectral analysis (which I haven't done yet) will confirm it. (I don't know what this recording has to do with Henry Ford's insincere retraction, unless Mr Friedman was simply giving some historical perspective.) Aaron Z
