For pictures of a large 4 inch diameter, 4 TPI tap that I sold a long

I'd like to see the tap wrench that goes with it.
This being a coarse thread, I would think that the wrench would be
operated by 2 people and should be 2 meters long.
I thought it looked fine for 12". The immediate thought I had was why
use a tap? The next one was probably it's used for field repair. What
a bear to handle. Whatever you're working on would have to be
vertical. I can't imagine trying to use that thing horizontally.
There is a reason why Fermilab surplused it unused. Whoever bought it,
probably did so to have a cute paperweight.
