Might be a good idea to better describe the taps. Are they hand taps, or are they intended to be power driven?

The grind of taps indicates their intended use. Hand taps have straight flutes with no change of angle at the cutting end. They don't direct the chip--it is intended to enter the flute, and be broken by reversal of the tap.

Taps intended to be power driven may look similar, but they have a lead angle at the cutting edge, either positive (generally a spiral flute) or one with negative lead, which deflects the chip in front, or down the hole. The number of flutes isn't a good indicator, as larger taps have multiple flutes, while small power driven taps have only two.

If all your taps appear to be identical, ignoring size, pitch and intended use (bottoming, taper, plug), post a picture of one tap, doesn't really matter which one. That will give readers an idea of the type of taps you have. I make mention because it's not as easy to use power driven taps by hand (hard to start, but they work well enough if you can start them), and hand taps do not respond well at all to being power driven.

The ones I got previously were all hand taps. I would think, perhaps without just cause, that three tap sets would inherently be hand taps.

Yes, they are all 4 flute hand taps. One if the boxes is open so you can see what they all look like.

Here is a pic of them out of box except the one Morse set that is sealed in box new. They are in the same order as above pic.
