Turned these 4 BlueLine combination wrenches at the flea market last Saturday. Top flight quality in my opinion. Always wanted a complete set. I don't think of Philadelphia as a hand tool mecca, but H-P did a great job for these. I'd be tickled to find more at the price that was paid for these 4. Interestingly, the 13/16" has a slightly different sculptural look, more like an S-K, or Craftsman Professional or JC Penney (both by S-K), but with a hex gullet. Hmmmm. A mystery I think that will never be solved.
