Hi there, and Welcome to the Board. Looks like to me it says 286/77 then Germany. Not sure -- but I think it might be West ?? Germany, but then from I know of West Germany pottery it would say W. Germany. Not sure IF all W. Germany Pottery says the W in the front. Others will know better....
...and I believe the first number is the model number and the second number is the height of it in cms. Do you have the measurements in both inches and cms?
Is there another number in the middle that looks like 40 or 48 in the very center of the bottom?
Again Welcome to the Board!!!
