Keith - I just came in from airing out the dog for the evening and checked on the saw. I was wrong on both the size and the accesories. It's only a 15". The model nbr is 40-150. I was thinking it may have had one of those quick release blade change gizmos with it, but had that mistaken for an extra set of blade holders (maybe for holding different type blades?). Other than turning it on to confirm it worked, it's been sitting on a shelf for 3-4 years since I bought it so I couldn't recall the details.
