I just returned from a trip to the ReStore. I now own four large KR Wilson combination wrenches.
13/16, 1 1/16,  1 1/8, & 1 1/4.  All that is on them is KR WILSON BUFFALO and the size. I know that KRW was the official vendor of tools for Ford cars from the teens to the forties. I did not know that they made simple wrenches. Does anyone have anything they can add?

I have a couple.  There are some on eBay right now.
Memory tells me that in the '50s towards the end of KRW tools they branched out into general use tools.  They appear to be Barcalo made.

Thanks Leg, I picked up a 13/16 Barcalo combination today and they are very similar, but the KRW is a bit longer. The forgings are the same and the size markings are identical.I did not know that they lasted until the fifties.

Buffalo, home of both Barcalo and KRW.

These are the photos.

Wilson clearly sourced wrenches from Barcalo. Here is my small Wilson Buffalo combo wrench with some of it's Barcalo cousins. Barcalo was a large contract supplier to others, including Montgomery Wards.
