Need help. I don't have any photos to share, but did see some pics on a cell phone.
The bike is a Super Grand Prix, said to be late '60s or early '70s. The Raleigh catalogs dispute this as I can't find one until around 1977.
But the other thing is the bike features cottered cranks and the photos I've seen on the internet of 1978 SGPs have cotterless cranks.
The color scheme is gold with black headtube and detailing. The bike has chrome fenders, don't know if they are original.
Bike is in outstanding shape. Owner asking $100.00.
Oh, BTW, the bike has 27" wheels. Some years they had 700c, but this one has 27".
Finally, it seems that the bike likely has 20-30 tubing. Did it vary depending upon the year, or is it all the same?
