Is the internal thread not simply for the crank extractor tool when you want to remove them..........................and give them to me.  :LolLolLolLol:

Those Cook Bros Racing cranks pictured are the later ones usually made for the MTB market and yes, mountain bikers might have run crank caps on them to keep the mud out. Early Cook Brothers Racing (italicy font) BMX cranks didn't come with a cap, the axle bolt was quite big and yes the threads were mainly for a crank extractor.

so any idea when mine date back to?

They look to be 2nd generation (1982/84 at a guess) - any more photos?

- Are the arms etched or is that a sticker on them?

- Do they have a notch cut in the back of the drive arm or are they both perfectly smooth?

3rd generation Cranks have the Larger text and often have a small notch cut in the back of the drive side for chain clearance.

4th generation Have the hollowed out arms and these are mountain bike XC cranks.
