Search ebay for "craftsman 41053" and you'll see a bunch of variations. flat, philips, regular, stubby, in both solid red and red/clear handles. I didn't think the info between the number and WF (G, K, II, "square", etc) was part of the p/n, but maybe it is? Or maybe 41053 is the p/n for any screwdriver with a red handle?Part number is for a flat tip common driver. Factory mistake tool which is not unheard of.
IIRC, those red handle drivers where sold loose in various limited sizes as singles and where usually in buckets at the cash register for impulse buys for like a $1 or so apiece.
