I don't recall seeing what you did to get the final finish to the fingerboard. Did I miss a video? I have banjos, I watch banjo videos on youtube, and got the first "Mike's dad's Gibson" video in my youtube feed. I watched it and I've been hooked on watching them all ever since. I'm amazed at the extent of the equipment you have, as well as the time you've taken on it. I hope Dave told you beforehand that he was going to sell it, and you were able to say that the cost of restoring it would be recouped when he sold it. If he didn't get on with his dad, he probably HATES banjo music! I'm in London. Do you know an English banjo player called Bill Peck? He used to live in California and come back to London for the summer, where I played with him in the 1990s.
Man this Bowtie sounds fantastic...nice playing Dave!! FANTASTIC job on the restoration! Your skill and craftsmanship are amazing. Some lucky banjo player is going to get a fine instrument!
