3 assorted size bottom taps

Of the 3 taps I can only make out the size and brand of the smallest tap, it is a: HY-Pro 5/16-24 NF HS GH2 625-24 Z. Tap has a taper start but is a bottom tap.
Other 2 taps of different sizes but very similar in size. One tap has tapered lead like the 5/16 24 while the other is a stright bottom tap with no taper at all.
Taps like new and very sharp indicating minimal use.
