Good day everyone! I stumbled upon this thread doing a little looking around the forums. I am the supervisor of the band saw department at Grob, Inc. You did score a great saw! That is our old Cut Off saw. Judging from the pictures, it is a CO-18 model, meaning the throat would be 18". The first one was built in 1948, and the last one left our shop on 3/23/1965, with a serial number of 157. At best, your saw is almost 40 years old, but could be considerably older. As a point of reference, we still have some parts in stock for this saw if you ever do need them. Not all parts, and once they are gone we aren't making them any more, but if you do need something, feel free to look us up at
www.grobinc.com and inquire. Many people loved the Cut-Off saw, our employees inclusive. We currently have 4 of them operating in our factory on a daily basis.
