WANTED: Polydor Alum soundbox

[Viva-Toenail]

Hello all,

I’ve been on the hunt lately for a Polydor “Alum” soundbox as pictured below. It was made by Polyphon / DGAG in the late 20s for the German gramophone market of the time (and likely the export market as well given the “Polydor” branding in the name / on the rear casing).

I’ve tried asking many of the known German spares sources but none have had any. Should anyone happen to have this soundbox, kindly send a PM.

Thanks!
