I found another "treasure" in that lot of pipes I bought at auction a while ago. I was cleaning up one of the "chaff" pipes from the lot, and wanted to see what I could learn about it. It had a rather curious stem/stinger arrangement that had me baffled as to the purpose. It was stamped with only "Holland Heine's Pipe" and "U.S. Patent 2,166,537". A search for Holland Heine produced no results, but when I did a patent search, this came up: http://www.google.com/patents?id=0Z...urce=gbs_overview_r&cad=0#v=onepage&q&f=false Be sure to scroll to see both pages in the link. I don't have any pic's as of yet, and truthfully when the pipe is assembled it looks like a quite unremarkable straight billiard or pot, depending on who's shape chart you follow. Submitted for curiosity and historical value. Enjoy!
