But as someone who lived through the controversy the headstock counts for something. If a Burnside was supposed to be a Guild then the headstock would have said so, right? DeArmond by Guild is waffling, but if it was supposed to be a Guild it would have said Guild by Guild.
We can choose how we define our collections but at some point we need to start with the definition of a manufacturer with a legal right to use the name.
I get your position (which is part of what makes this fun), but ny counter to your statement is that Guild had the legal right to put "Guild" on their Burnsides, Madeiras, and DeArmonds since they (or Fender as the case may be) owned those names - they just chose not to (I assume) because at the time it would have weakened the brand. Today we live in a completely different consumer market where import versions of historically US-made brands are the norm so there's no uproar like there would have been 25 years ago.
I'll admit that my count includes DeArmond and Burnside but my spreadsheet separates out "Guilds" and "True Guilds" which would probably irritate everyone while also adding veracity to your argument since I include Newark St. guitars as "True Guilds".
I also just noticed a quirk where the totals didn't line up, but found that I had listed my Crossroads Doubleneck as both an acoustic and an electric. I'm not changing it.
That doesn't affect my "Total Guilds" count, though.
