    Name that company logo game!

    I'm trying to identify the maker of the crankarms on my Borthwick tandem.

    The chainrings and bolt covers are Specialized, but I don't think the cranks are....

    The ones on the left say F-12, the triple chainring says F-6 and the pilot right says E-7

    I can't identify is the logo on the cranks.....

    Does anyone know who made these?

    They are Specialized branded but they look like Sugino AT cranks. Late 80s to mid90s.

    By the way, the chainring bolts are backwards. The hex heads should be out.
