I have a Willis Landshut Goldene Medaille. What do I own? Updated with pictures

[lasme]

I have a Willis Landshut upright piano. The only thing I know about it is that it is German made. I would really like to know when it was built, what kind of quality it is, and what the value of it is. I figured the manufacturer must have gone bust, since there is no good info online.

It says "Goldene Medaille 1933-1953", on the left side over the keys in golden letters, and the serial number is 14737.
It is in good condition, but not tuned as long as I've owned it(4 years).

Please help:)

Google for Willis klavier and have a look at the German sites and images that come up. There are quite a few examples at good prices indicating that Willis was of good quality.

I checked it out and with a bit of Google translate i got closer to knowing the price range it is in, so thanks for the tip:)  i'm still missing info on the company that made it. Isn't there some sort of database on the serialnumbers somewhere??
