Completely restored pre-WW2 Hohner Double Ray Black Dot with original zinc reedplates in the keys of BC. It is a 3 voice instrument in a Pokerwork sized case. I believe this was originally 3 voice MMM but was nicely converted to LMM by fitting a larger middle reedblock. This was made in Germany circa 1938. It is in good condition overall. The painted wood case is in good structural shape but shows some wear. The bellows are reasonably tight and have been retaped. The gaskets are modern closed cell rubber foam. It has 21 treble buttons and 8 bass buttons. The original treble, chord and bass reeds are steel on zinc plates and have the Hohner “H” marking. The valves are modern plastic one way valves for long trouble free life.
Another feature of this 3 voice box is on the bass/chord side. Rather having a 12 reedplate chord block it has 16. This gives two root note reeds an octave apart and the third and fifth to make the chord. It also has a mechanism to activate both the large bass reeds and the two octave reeds on the chord block when a single bass button is pressed. This provides a very rich 4 voice (four octaves) bass note. When pressing the chord button it activates 4 reeds on the chord block. The air button hole is also larger than a standard Pokerwork to gulp air quickly when desired.
As the photo shows, the metal grill has slight rust but no major dents. The front grill cloth looks original. The rear grill cloth has been replaced. The wooden keyboard is intact with no cracks or missing pieces. Often there are cracks or entire sections missing between keys on some of these old accordions. The bass strap has been replaced with a new, velcro adjustable model-an improvement normally only found on more expensive instruments. The bellows straps have been replaced. The thumb loop has been removed. It has shoulder strap brackets. No strap included but one can be purchased separately.
Another improvement is that all the pallets have been repadded on both the treble and bass sides using modern felt backed leather pads. This not only quiets the button action but also provides an excellent seal. I have tuned the treble side to near dry. The tremolo beat frequency is about 0.8 Hz low notes to 3 Hz high notes. I tuned the lower octave reeds in between the middle octave reeds. I also added a anti-resonance cross-bar between the treble blocks. The bass buttons have new white tops and have had black felt cushions install under each. Final tuning occurs in situ with the reedblocks inside the case.
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 174 reeds in this instrument and every single one has been tuned. I repair and tune button accordions and have specialized in older Hohner button boxes.
