Made in Italy? The tremolo is the same style as was used on the tremolo version of the (Burns) Baldwin 706 guitar which was exhibited at the same trade fair and also used Italian parts.
The full picture shows a separate control box with similar selections to the guitar itself. I wonder if a 3-pole (Tip Ring Sleeve) jack lead was needed? The box seems to have the same pickup selector as the guitar, which would be difficult without three wires down the cable (or modern digital technology not available at that time).
With all that electronics and either a 9v battery or multiple 1.5v cells on board, the guitar would have been really heavy. Perhaps Bruce has been misquoted and what he's actually saying is "Hank will be puffed out with this"
