From the mark I believe it dates to the late 1920s. It is 40cm tall and the plates are 20cm in diameter.
All parts have the same Walker and Hall mark and number. I can't see any dents or dings. There is a fair amount of scratching but no plate loss.
There appears to be one very small area on one plate where the silver plate is a bit worn/duller (the silver plate is just a bit thin I think) and there are a couple of areas of mild corrosion (two millimetres). As you would expect from this maker, it is superb quality and will give years and years more service.
