A few notes on the Fender viddy for those who might be wondering:
0:51: this looks to be the initial body formation of what might have ended up as a slab Precision bass. These were originally made for the UK market in the '50s, but I don't know if they were still in production in '59. In about '66 they made another run for the US market. They lack the body contours that you can see being added from 2:33-2:41. I suppose that made the bodies of higher mass, which might have added some thump to the low end, but those beasts can be very heavy.
5:10: this Stratocaster body is lovely. I've nothing to add to that.
5:33-6:00: the women appear to be doing pickup winding and other electronics-related prep, but I can't be sure.
6:23: What appears to be a tobacco sunburst Strat being held by the shirtless man would likely fetch $50,000 or more in that condition today.
6:36-6:42: Installing strap buttons (sure looks that way to me). What's odd is that, in this era, Fender had the "upper" strap button on the back of the headstock, but may also have offered the upper bout of the body option, which is what looks to be going on here.
6:44-7:10: final touches to that tobacco sunburst Strat. Shirtless dude is a jazz guy based on his voicings.
