1930s Kalamazoo KG-21 (Gibson-made) Archtop Guitar

It's been a while since I've worked on a Kalamazoo KG-21. These were made quite a bit in the mid-'30s but petered-off in favor of the 16" models rather quickly as far as I can tell, production-quantity-wise. This one has a factory order number that looks like 836 but it's pretty smudged. I would guesstimate 1935 as the year.

Anyhow, this was in for "the usual stuff" and turned into a nice, chunky-sounding player when it was done. It's in relatively good shape compared to most of these and is crack-free and has just the right amount of pickwear near the fretboard.

These instruments share the L-00's body shape and have deeper sides than your average archtop.

Repairs included: neck reset, fret level/dress, side dots, bridge adjustments, tuner adjustments, cleaning, setup, brace repairs (to the rear).

owner here — thank you again for your god-tier work on this man, it's a totally different instrument now.

do you happen to have a recommendation for a hardshell case for these? from what i've read the unusual body shape makes it tough to sub in a mass market one...

but of course i have no idea what i'm talking about.
