i wonder if he actually got it refinished, in the process, because is it not weird for me to find this on a 50 year old guitar? unless, i guess, it's been like that for decades. but, it's possible that the guy that refinished it went over an 1/8th an inch, and then couldn't glue the bridge back on. oops.
but, i'm going to need to get some acetone or something as well, because there's gumps of what actually looks like three types of glue - crazy glue, yellow wood glue and white glue - on both pieces, and i'm never going to succeed in scraping it off.
my best guess is that the white glue failed, so they moved to crazy glue. lol.
