The bing 130 12 or Vulcan as I have read seems semi scarce I think I have seen 5 sell on ebay. The lines are a fairly easy fix, good luck with burner, seems about $100 if u can find one. Same with chimney about 100 They are worth between 400 to 800 depending on condition. 1637 is most likely stamped at bottom of cast iron base. These are known for the extra portion on the top as dickopfs [spelling] in german.
