Hello friends,
I was enjoying my Friday browsing through German vintage archtops over on Reverb when I came across this thingy that I haven't seen before in my weeks and weeks of experience investigating archtops.
I'm not sure if it's a guitar thing or an archtop thing, because I've never come across one in my months and months of experience with guitars.
Please identify this thingy. It's attached to the back of the upper bout on the bass side. This one is white plastic. It's visible in the first photo and quite clear in the eighth photo. I've also seen one in metal.

Many thanks!!
