45 pc tap and die set ... I believe its Iilco, but cant confirm that. metric from ~6 mm to 24 mm, and SAE from 1/4" to 1". Per pics, in, near new condition: Purchased for emergency repairs on an off-road trailer (thus why I cant recall brand!!), and not used since. I no longer have a garage, or storage, so purging all of my extra equipment. Paid something like $250 for it, but I just want it out of my way. $100 obo.
