I got this from a Danish guy who worked for House of Denmark and Dansk for many years. He would bring home the broken floor pieces that were headed for the trash and fix them up in his shop - nice double-viced handtool bench in there (that he was keeping or it would have come home with me). Most of the wood he had was some type of discolored white oak - almost looked like reclaimed lumber or possibly barn wood so I passed - (however I did end up going back for it and picked up an old Bang and Olufsen stereo as well).
After I loaded up I asked if he had any of the dirty paper or the arbor wrench - he said no and I about drove off when he said "I do have a Dado set that was given to me with saw" - he threw it in for free. Thought it might be of interest - I've never seen a box that had to be renailed shut like this one - still has the original oil paper:
Delta 6-in. Dado Head No. 33
No idea where I'm gonna put this saw yet - it joins my 790 and 7730. I really don't have room or need for 3 saws - man the slope is slippery indeed.
