I did find an old Craftsman router bit set for $5 - has probably twenty bits in it, of which 90% look unused - I'd guess they are from the 70's or maybe 80s based on the packaging, so definitely older and from the better quality Craftsman era. I also found a Marson Hp-2 riveter kit for $10 that is seemingly new and looks similar to this:

I don't have a riveter and it said Made in the USA, so was pleased with that find. I also got several 3+ ft Jorgensen bar clamps for $5 each. But the most intriguing item was a "Mitutoyo Combination Set" (model 180-905) still in the box and seemingly unused - it looks just like this:

I paid $50 for it - it was an impulse buy as it just looked cool and seems well built and seemingly very accurate...I'm not really even sure how the center head attachment works or if this was a good deal (?) I have lots of squares but no higher end uber accurate ones, so hopefully this fits that bill and I don't have a protractor...not even sure if this set is more geared toward metal working than woodworking? Anyway, I'm a sucker for quality tools, so I sprung for it and hopefully it was a good buy.
