Per the video, it came right after the first two Hawaiian frying pans. Sounds great as a slide guitar.

Wow! That is impressive
An 86 year old electric guitar & it still sounds great!
Despite the steep asking price, I'm surprised it hasn't sold yet. There are people who will spend well into six figures for 58-60 Les Pauls, this is a one-of-a-kind historic piece.
