Thanks for the kind comments. By way of background; before scrapping then for a renovation, a builder friend offered the legs to me. Google Lens located a
2019 post here with the B & S 1906 Catalogue page referenced above by BlackVersa2. The description there affirmed my interest and clarified some details that weren't obvious to me.
For the top, I visited
Sawmill Sid here in Toronto, intending to pick up a piece of live edge maple. He had a stack of 10/4 fir salvaged from the Gooderham & Worts distillery (built ~1860). The pieces were only about 72" long by 6" wide. The edges were rabbeted for floating splines, some of which were still hanging on. The material was in rough shape with serious water damage on the upper face and edges. There were quite a few 1/4" spikes and other forged nails. My metal detector earned its keep on this project! The legs demanded a beefy top so I stopped planing at 1-3/4" even though that left some punky stuff on a couple of pieces. Despite its age, the fir was very oily and the milling liberated a fantastic aroma. Fir is a bit soft for a working bench top but this is not going to be pressed into service & I love that its vintage complements the cast iron legs.
