[SEL] valve spanner wrenches

[bill at antique-engines.com]

Yes.

Lapping uses a tool spun by hand, or using a crank.
"Tappet wrenches" were thin profile wrenches used to get into the tight
spaces for setting the valve clearances. (when cam is on base circle, the
distance between tappet and valve stem tip)
