Tool query...

While helping out with a pre-buy last spring, I saw a tool I have to have.
It was a hollow steel tube, with a t-handle and air hose fitting on top, and
a spark-plug-thread on the bottom. You screwed it in to the cylinder using
the t-handle, and hooked the compression tester to the air fitting on the
top.

The guy who's tool it was said he'd seen them for sale before, but the
one he had was custom-made.

Anybody ever seen one? I can make it if I have to, but I'd rather buy one.

Thanks!
