What years were these two wrenches originally used? The lower one is nickel plated by the way.
The TT wrench was used from 1917?-1927. The spark plug head bolt wrench was the earlier version. 1920 and before?
The one with the extra hole looks like TT-5893 (spark plug, head bolt, rim nut) for trucks. The other one looks like the regular 2335 issued 1915-1920. I don't believe I've ever seen one nickel plated.

Just what the heck was the original finish? Almost all the ones I've seen are either rust or a thin but tough black "wash".
