I understand that you're talking about Indestro, specifically, and I know that Duro Metal Products tools were not always identical. But I think you would agree that most of the production is either in the 'very similar to near identical category', if not always 'identical', and to that end, the 1939 Duro (No. 39M), the "1940" Duro, and the other 1940 Duro (No. 40M) catalogs do provide some help on the near end. Conversely, I use the heck out of the 1948 Indestro catalog (No. 16) to help close the postwar gap between Duro's 1940 and 1951 catalogs. Not telling you anything you don't know. And I don't know if the '39 and '40 Duros are any help with respect to that particular box. Just as a general comment for all the D-I guys, I have found those overlaps helpful.It would be really nice to have some documentation for the periods between 1937 and 1948
I added a correct ratchet, extension and newer Indestro spinner to the set since I’ll never find an original Duro spinner. The exterior of the box will need paint.

Not all water pumps used pliers. Model A and T Fords used a hook spanner. But your point is well made. I always called them water pump pliers, also. Mostly referring to the type with offset holes to grab rather than the slots.That would be an awesome accent piece for a 'History and Evolution of Water Pump Pliers' display, especially for everyone who calls them "channellocks" and looks at you like you have three heads when you call them water pump pliers!![]()
The whole point of their evolution is that they were preceded by hook spanners and SOE wrenches with thin handles and angled, wide mouths, some smooth, some with flare or box end like teeth. But as I know you are well aware, water pumps came in different sizes, necessitating general mechanics to have a wide range and silly number of water pump wrenches. Just to delicately tug down (and some would say more art than science) a nut just right (not too tight, and not too loose) on packing material. Hence the innovation in the single adjustable tool.Not all water pumps used pliers. Model A and T Fords used a hook spanner.




I got tired of looking at the rusty exterior of the box so I sanded it down and painted it.










But made by Indestro? argh, maybe not, misread 4.c post. Guess I will move it to the Dunlap thread. Thanks for pointing out my miss.I think those were Dunlap.

Uh huh. Like the difference between fishing and catching. Still, much of the pleasure comes from the search and the discovery and in my seventh decade I know that time is precious in much different ways than it used to be.That sums it up for me
I was about to congratulate you, then realized I'm also in my seventh...here's to a few more. Cheers!in my seventh decade I know that time is precious
