Two 14" blades or a single up to 22" maximum. It was a dual arbor saw, so common to keep a 14" rip blade on one arbor and a 14" dado stack on the other, selecting between them by spinning a carriage positioning wheel. Pretty cool machine, and very handy not having to constantly change blades during a project. I also have a big radial arm saw that could take blades up to 20", although I have it presently fitted with a 16" crosscut blade and guard, so the table saw only had to be used for rip cuts while the radial saw did all the cross cuts.
When first out on my own, struggling to amass tools and a real woodworking shop while paying my first mortgage, I found that good commercial-quality machinery was pretty expensive, but used industrial-grade machinery was basically free to anyone who could move the stuff. So, I went from shopping 600 lb. Deltas and Powermatics, to 2000 lb. Olivers, Tannewitz's, and Crescents. I had a jointer that looked like an aircraft carier, the aforementioned table saw, a 32" bandsaw, a planer that weighed more than my pickup truck, etc. All were free or nearly free, since commercial shops couldn't maintain insurance buying such old equipment, and few hobbiests have the wherewithal to move or power that equipment.
Like with anything, timing is everything. I was amassing equipment just as the foundries all over the northeast were shutting down their pattern-making shops, and auctioning off equipment. Of all industries, foundries had the very best woodworking machinery, way better than any cabinet maker, due to the scale and complexity of wood patterns made for casting iron and aluminum.
but I do learn what hurts and try to avoid that, unless it just minor like wasp stings, etc
