I use wood handled drivers almost exclusively. The square handled ones, as shown above, were offered by MAC, Irwin, Grace, and probably others. They are more common than you would think and tend to be marked on either the ferrul or painted/pressed on the handle. Snap-on and Cornwell also offered square handled drivers, but without the notches. As with everything else the sold, they are branded somehow.
Stanley offered many drivers in wood over the years, as can be seen in their catalogs. Rounded handles, sometimes used by Bell Systems, they are pretty common as they were offered for many years.
Plomb/Proto offered an eight-sided driver line for many years, only stopping relatively recently. Marked with either a red or blue line to denote flat-head or Phillips, not as easy to find, but a lovely driver.
Then there are the round handle unmarked one that seems to be in every old tool setup. Who knows the maker or the seller at this point, as they aren't saying. The date?
If it says Taiwan, it isn't that old, nor collectible. I see these with the handle split as they didn't use good wood that had been dried enough.
On most of them, finding the date of manufacture is the same as anything else by a manufacturer. Check the logo, is there a circle R, etc.
