^ I have yet to sit down and try to determine exactly how many iterations there were of that "Open-Box Wrench" style that Indestro made.
Some have "Indestro" forged into the panel.
Some have "Select Steel" forged into the panel.
Some say only "Forged in USA".
If you look closely at the catalog illustrations I posted just above (which is just a small sampling of the listings for that style wrench) you will note there was no shortage of choices. You could have 4 piece, 5 piece, or 6 piece sets, in either dull finish, or with polished heads.
They must have stamped them out by the millions - they were selling them to hardware stores, auto parts stores, Montgomery Ward, Western Auto, True Value, and other accounts.
There is currently a set of three listed on Ebay which by every detail appear to be Indestro made, except they are marked "West Germany". A seller in Chicago had a couple a few years ago, but I think he finally sold those.
Short version: that little 907 with the 1/4" 8-point opening is like trying to find an early black-finish Walden 6-inch extension. (But probably not as difficult as locating the missing 9/32" drive 9/32" "C" series Craftsman socket one of my sets is missing.)
