Answer 1

I found this on ebay (there are presently 30 pieces by the company for sale). I don't know the size of your piece but you can use them as comparable values for your vase. I hope this helps!:
GORGEOUS ART NOUVEAU JUDENDSTIL KAYSERZINN PEWTER VASE
Item number: 220141365831 Presented is a wonderful old Art Nouveau pewter vase. This vase was made by J. P. KAYSER SOHN, also known as Kayserzinn. They were Germany's premier Art Nouveau period metalsmiths, and produced many fine decorative items. This piece is a rather simple vase with a wide opening at the top. The vase is decorated with gorgeous flowers in relief. The pewter could use a cleaning but we will leave that up to the new owner. The vase is marked on the bottom with Kayserzinn and the product numbers 15 and 4083. This is an excellent old piece with only basic wear. There are some very small dings to the top rim and a little bend in the lip of the bottom. Otherwise it is in great shape and there are no cracks, no breaks, no repairs, and no problems of any kind. The vase is 6 3/4 inches tall. It has a 'Buy it Now' price of 150.
