(Sold) Criterion S-1 Boring Head w/ 3/4 fixed shank. Accepts 3/8 tooling. Head is 1 1/2 on all 4 sides. Nice little tool purchased for my personal stash from a retiring toolmakers personal stash back in early 90's. No idea of actual age, has never been engraved. Not a 'shop' tool, used sparingly. Shank does have usual marks from various toolholders, etc. Nothing that impacts the precision. Good screws, dial accurate, etc - reason for sale is that I purchased Ramsey Tool Precision head. This one hasn't been used since.
I'll toss in a longer length HSS boring bar that does not appear to be used, no idea what brand. Been in my box for years. $65 shipped
