Milling machine fluted bits

So I'm cleaning out my shelves and just found these. I don't remember when I got them and never used them. I can't read the info on the upper part. Chime in if you recognize them of just buy them and figure it out later:D
$40.00 for the pile + sh/pp fees, 22 of the larger sizes, 32 of the smaller.
