Hello! I inherited several model steam engines through my mother. Most were exquisite little engines by Stuart Turner. I am not a collector so I have been trying to sell them at a fair market value on ebay. These things are quite valued and sell quickly! Yesterday I found another box in the attic with this extraordinary piece. It is about 12 inches long and 8 inches high. It weighs at least 10 pounds! Looking around on the internet I found it to be a hit and miss that maybe runs on steam instead of gas? My questions are, does the "B" stand for Bing, the German toy company? I looked at some of their stuff but found nothing like this. So, I would like to know the manufacturer and what I might ask as a fair market price. These things are really cool, and I like them to go to people who really appreciate the fine workmanship. Thank you for any help you can give me. Oliver
