50's Chainset 46/49 - Lenton Grand Prix

'Lil Knee Scuffer
Hello, I'm in the early stages of restoring a 1958 Raleigh Lenton Grand Prix and in need of a chainset that's time appropriate for this bike.

The correct chainset is a Williams "Heron" Double, 46t/49t crankset.

Here are a few pics of others chsinsets that were equipped on Lenton GP's

I recently missed out on one on EBay. I was outbidded.

Thank you.

KMC makes "5-6-7 speed" chains which will probably work for you.
You could probably also get by with a modern 8-speed chain

oops, you're talking about chainrings + crankset.
You could make a nice half-step double with Stronglight or TA alloy cotterless cranks.
It would require a BB change with the correct cups.

You could also check ebay for cottered crank.

You might also request to Dale for access to Classic Rendevous google groups.

You'd need a g-mail account, and e-mail him for access to the board
