I'm trying to discover the origin and make of my father's piano. I believe he bought either in the eighties or early nineties in London. It has an Amadeus nameplate and between the tuning pins on the cast iron frame is also an Amadeus trademark and serial number D010503. It is a 110 upright console in a polished mahogany finish. My piano tuner thought it might be by Samick but the serial number doesn't match. I've looked at a fair few serial number listings but still can't match it and wondered if any one on the forum can help. I have attached some photos but my apologies as the sun was shining and you can see reflections in the gloss finish.
You could ask your tuner to check for any clues under the keys.
