The cloth on the exhausters is in near perfect condition and it seemed a shame to replace them, however the flap valves are leaky so they had to go. All bearings have retained their grease and are rumble free.

Similarly the cloth on the pneumatics is still almost like new. It took very firm pressure for that corner to tear. These instruments were often manufactured from very high quality materials.
After 8o years service these valves are in remarkably clean condition.


The expression box removed and looking pretty sorry for itself.

This one came apart very easily. It seems these later types were put together with long screws and gaskets saving a lot of work and potential damage.

The Duo Art Expression box complete and ready to refit. I have recovered the accordions with fine pneumatic cloth as an experiment after reading of others experiences. I can recover in quality pouch leather if required.

Modifications made to the motor switch for electrical safety. The mechanical action of the original switch is used to operate a microswitch fitted with a spark suppressor. Similar to those pictured below.

I have decided to replace the original motor in my quest for reliability and electrical safety. This one is evenly matched for power and RPM, has a capacitor start and run,
and the manufacturers claim that it should run for 20,000 hours under normal operation without maintenance. I have also replaced the leather belt with a modern ‘V’ belt as it was kinked and perished.

The original motor pictured here still runs though it gets very hot under prolonged load. It would very easy to refit it if desired to keep the instrument authentic but I would recommend a complete overhaul and safety check before doing so. I am not qualified to carry out this work but I am sure there are plenty of electric motor repair shops that would for a reasonable sum.








The restored piano action includes new hammers and dampers along with all springs felts and tapes.
Below is a detail of the resprayed backplate along with new wrest pins and strings.
The casework has been completely stripped and repolished by hand and the richness of the finish can be seen in these pictures above and below:
