Brian,
Yeah, those hammers will collect dust in my toolbox.
The hammer with the yellow paint and the two directly upwards of it are made by Streamline. You can tell a Streamline from a mile away with its distinctive football like shape and wide cast line running down the middle of the hammer. I have a tool catalog from Streamline that dates back to the early 50's. You can still buy Streamline today.

But with that said, Craftsman body hammers were made by Streamline and painted blue in Color. Mac Tools also used Streamline until at least the 70's, they were painted dark red in color. The hammers were identical other then the paint job and logo stamped into the handle. Streamline also made hammers under the label Nuapla(sp?) that featured fiberglass handles.
The work bench...LOL. Typically when I work on something the area looks like a bomb went, but I know where everything is placed. At the end of day it all finds it's home only to be scattered about again.
Can't remember without looking but this catalog is late 50's I believe.
