eBay: Vintage Blackhawk Adjustable Wrenches?

By Chuck Cage

post-bhadj.jpg

The seller of this eBay find claims that the items in the picture are “a rare pair of two different styles of Blackhawk vintage adjustable wrenches.”  They’re pretty strange-looking, and damn if I can tell what they are.  Have any of you seen these before?  For what are they used?  Let us know in comments.

    Reminds me of the crescent adjustable socket wrench.

    They look like internal/ external drain plug (or possibly drum plug /bung) wrenches.

    Andy has it. It’s a bung wrench with a plug wrench at 90 deg.

    Yep thats a bung wrench! The gold hue is a dead give away as most of these are beryllium, so as not to create sparks. Generally speaking sparks and many of the thinks shipped in drums are a bad combination.

    Here’s another. Think it may be an early automobile wrench?

    Looks, to me, like an old-style tube flaring tool.

    Looking at the square drive in several sizes, my guess is that they are universal tap handles. Hard to gage the size, except for the knurling on the knobs, but they look about the right size.

    The best bicycle wrench I ever owned, circa 1957. Twist the handle, tighten the wrench around the nut, then spin the wrench on or off.

    You can see them at Alloy Artifacts on google under Blackhawk manfacturing history. Drain plugs wrenches.

    My Dad has one of these that belonged to his Dad. He says they were used for checking rear ends.
