Re: Identify this bowlback/tater bug?
From the pickguard and headstock shapes, I'm guessing an American Conservatory or other Lyon & Healy brand; Chicago-made, early 20th century. Fancy pickguard inlay, but plain dots on the fretboard, modest number of ribs in the bowl, not rosewood, which is what the fancier bowl-backs tended to be. Mid-price.
Must be well-constructed; most bowl-backs wouldn't pack enough of a wallop to knock someone out. I save my National Triolian for when I need to use a mandolin as a blackjack...
