Sounds like class B; plate current flows for 180 degrees of the excitation
cycle.
On the issue of key clicks and class C: Up until mid to late 50's when SSB
came along, all of the ham amplifiers were class C and there was a lot more
cw then than these days.
The key click issue was handled by paying attention to the rise and fall
time of the cw waveform. Same thing happens today without our knowledge as
the radio manufacturer handles the issue in the design stage. As you may
know, some manufacturers do a better job than others.

I have an adjustable bias where I can run a little ZSAC for Class AB. But
I
can dial the bias until it *just* cuts off and I often use this setting for
CW. What class am I running when I do so? I've heard it informally called
class B/C. Running CW at that setting, or even a little deeper bias into
Class C territory does not create any reported key clicks here.
