hey i posed this question to the Classic Rendezvous list awhile back. wondering if anyone else has additional insights?

i have a raleigh, that's completely chrome.
the headbadge says "Raleigh Cycle Company of America", fastened by 3 rivets.
the headtube lugs have "RALEIGH" stamped into it.
shifting cables are routed under the BB via a plastic cable guide.
the rear dropouts and the seat stays are also stamped "RALEIGH".
the dropouts have drilled holes for racks/fenders.
rear brake cable guides and shifter bosses are brazed on.
water bottle cage holes are predrilled on the down tube.
brakes are long reach style, although it's hard to say whether any of the components are original.
the serial no. is 3KN0797 although it could also be SKN0797.
the previous owner said it was a Grand Prix, although he wasn't sure.
a few posters on the CR list thought it was a Huffy-made Raleigh.

any guesses on model? year? what the serial no. means?

aloha,
matt
