so you ended up with that set!
Rugged / Rugged / (see Fleet / Penens) / (possibly private label?)
I've never found
any documentation for "Rugged" - only the photos of the set on ebay, which apparently belongs to Oldtuleguy now.
The spinner looks somewhat familiar. If this is the same set as Oldtuleguy's (which I believe to be the case), I don't recognize the sockets, and the label doesn't offer any clues as to who it was made for.
I'm going with private label for some retailer or maybe a "second-tier" line (e.g., Thorsen's "Action")
