I have one of those in 12". It's a Zenith, but I don't know for sure who made it. I have a Bonney's patent hollow auger that only fits in it, because it's got that Fray chuck with its giant jaws and the shank on the auger is right around 1/2" thick, maybe a tad bigger.
So my pricing had me leaving the meet empty-handed. Not the first time. But it also likely left the seller dragging the planes in tow behind him on HIS way home I was more curious if I missed a decent plane!
I don't have a 3DBB, but I do have a Fulton 3709, which is identical save for the name and the paint. I love that thing, and they've both got that Millers Falls steel. No worries of dulling that iron on the first pass, nope.
