The more I look at your item, the more it appears to be a cookie jar rather then a stein. does the lid hinge? or does it just come off? The numbers would me manufacture pattern numbers and possible craftsman. Also can you give the size of the item, looks to be very large in size. Would have to see a pic of the hallmark to ID the maker. However without that if it is a stein this would be a very unusual stein to say the least and would easy fetch around $50.00 if not more. If it is a Cookie jar then maybe a bit less because their are many unusual cookie jars, even though Cookie jars seems to be a bit more collectible.
