Respect! Great idea sir. Golf-clapping to you. If I may pick some nits: the first pic above is of Paul T.'s 1936 bass, the Audiovox Model 736. Bud's 1947 (-49?) recreation, the Serenader bass, had small differences: a concave profile in the upper "cutaway", an edge corner under the treble side of the bridge, a smaller scratchplate, the fact it had no frets above the 12th, different headstock: (From this thread and post: Tutmarc audiovox model 736: where are they? ) Here's a lap steel from the same years, with clearly the same basic shape: 1940 Tutmarc Bud-Electro Serenader Dark Cherry > Guitars : Lap, Pedal & Table - Mike & Mike's Guitar Bar Your mentioning the Serenader in the Audiovox logo (on an Audiovox-version inspired bass) would be a conflation of the two Tutmarcs - unless I'm mistaken and the "Serenader" name already appeared on Paul's Audiovox basses from the 30's, but, as I said, AFAIK it was used by Bud in his instruments from the following decade.
