...from a local company that does clean-outs of basements, barns, attics, etc.   

Very complete precision screwdriver set - it's from Taiwan.
5-1/2" adjustable auto wrench - with unfortunate crack in the lower jaw below the adj wheel - this will get brazed.  I've never even seen one this size - even in photos.
The tool at left is ...what?  It looks like a countersink but the teeth pattern are diagonally opposed every quarter way round.  It looks like it would be for deburring or chamfering a drilled hole in metal.  The tool is stamped GD9K and below that FORD and a round logo of a saw blade with a script letter F inside.  Looks like something I will use a lot.
Impact driver - also made in Taiwan - but I need one for work.
And it didn't make it into the picture but I picked up one of those little stamped magneto wrenches with feelr gaes attached.  This one is stamped SPARK and has a 3/4" spark plug wrench and 0.035" gage; the other side is stamped MAG and has a 0.020" gage; and of course the other end of the wrench is a screwdriver.

Nice little haul!

Is that angled tool bit something that would be used to repair valve seats possibly? Not in an engine necessarily, but maybe in a water or hydraulic valve?

I'm not certain but I would guess not for two reasons.  The cutting teeth are a bit coarse for a faucet/valve seat and the company logo is a saw blade (letter Fin in round saw blade) which says to me not a plumbing tool company.

Had the brazing outfit going today so took care of this.  Not the best job but functional.  Used nicklesilver brazing rod. It didn't want to go into the crack at first so it's a little messy.  Hmmm, well the brass hardly shows in the photo but you can just make out the excess metal, I think.

Good repair. See kids, that's how grandpa fixed stuff years ago. We didn't have the money to just toss something, we fixed it.
