Almost every estate auction tool lot seems to have one of these flat plate multi wrenches. They're "bonus" items received when bidding for something else. I've just been dumping them in a box, their interesting complex shapes forbidding me from scrapping them as I wait for that once-in-a-lifetime opportunity when one might come in handy, and now I have a "collection"
They're usually called "bicycle" wrenches, and a couple of mine are stamped CCM (the two widest ones), but they seem to have been made for all sorts of machinery besides bicycles. Most of them are not named and their origins/purpose are a mystery, but I have one stamped "Penn Reels" (top left), a "Nordson Corporation" (top right), and a "Lamps Lanterns" (bottom horizontal)
Perhaps you can identify some of the others.
