TREE RING RESEARCH DJOS INCREMENT BORER CORE EXTRACTION
Up for auction is this hard to find tree aging core extractor. This is a neat portable little tool that is complete. These are used to tap into the tree. You tap the borer into the tree then you use the fluted type needle to extract the core. Once the core is removed, you count the rings to age the tree. The core then is placed back into the tree and sealed and t's no damage done to the tree. Sometimes they keep the core. The length of the tube is 12 inches. This one is kind of interesting in that it's stamped "DJOS SWEDEN" but on the other side it's also stamped "KEUFFEL & ESSER CO. 4 1/2". I'm unsure of the relationship of the two companies. Everything appears to be intact and functions as it should. It could use a little cleaning and probably with some WD40 you'd be able to remove the surface rust on the metal which is not bad but it is present. You know how hard these are to come across so don't pass on this one. Please look at the pictures and bid accordingly. Please contact me with any questions. Thanks for looking and good luck bidding. Note: due to recent problems with insurance claims on international shipments involving FED EX, we no longer ship international. Also, please do not ask us to ship via FED EX as we will not patronize that company. Sorry.
