Nice early M.Hohner button accordion in the somewhat rare key of D, just tuned. This was made in Germany in the Hohner factory. It was shortly after Hohner acquired the Koch accordion company and features Koch steel on aluminum reedplates both treble and bass sides. It is in very good condition overall considering it is probably 85 years old. The blond pressed wood case looks great. I have done just about all the possible restoration on this instrument. The wooden grill is intact and there are new grill clothes front and back. The wood case is in great shape shows moderate wear for an instrument of this age. The original bellows are airtight and have nice colored papers and red taped edges. I installed new bellows gaskets on both sides. It has 10 treble buttons and 4 bass buttons. The treble, chord and bass reeds are steel on individual aluminum plates and have the Koch Goat’s Head marking. All the key pallets have been re-padded with felt cushioned leather. The bellows are quite tight now.
The original leather one way valves on the reedplates were all replaced with modern plastic film valves on both the treble and bass/chord reeds for a long trouble free life. Tuning occurs in situ with the reedblocks attached to the soundboard. I have shifted all the reeds to A=440Hz reference.
The wooden keyboard is intact with no cracks or missing pieces. The thumb strap is functional. The single row keyboard has a removable back plate. I have shifted the long piece of felt that quieted key presses slightly so fresh felt is under the keys when they bottom out. This design nicely stops the buttons flush with the keyboard unlike most standard Hohners.
I have added a new pair of shoulder strap brackets. I will include a used strap if requested.
Most of these older Hohner accordions are found with numerous notes out of tune, wheezing or not sounding at all. This was just fully tuned. There are 60 reeds in this instrument and every single one has been tuned. The treble reeds were tuned with a tremolo beat frequency of approximately 1.5 Hz at the low notes gradually rising to about 5 Hz at the high notes, for a sweet tremolo. It is ‘drier’ sounding than a standard Hohner. I used Viennese style tuning where the reeds are tuned plus and minus from pitch so the average of the two together is right on pitch.
Unlike most of the older Hohner boxes purchased used, this is ready to play without further adjustment required.
