G&J Rambler w/ curved crankset

[Jesse McCauley]

Here's a stumper for you fellow TOC'ers-
Did G&J ever use this crankset in a factory capacity or was this an aftermarket addition to the frame?

I only recall seeing these cranks advertised on Ide bikes but I'm always learning!

Luthy had curved crank arms. I have a few pictures of that.

Sure looks like a G&J chainwheel and connection- are the arms seperated from the sprocket star with common connection?

Luthy had curved crank arms. I have a few pictures of that.

The Luthy arms are double curved I believe. My dad has one.

I had an Ide and they looked just like that. My Ide was a 3 piece crank, so I'm actually leaning toward this being original ?

This Ide advert seems to shed a different light on the hardware though, not cottered and different bolt pattern but the bend of the arms is the same it seems?

I do not have proof but I think original G&J crank.

So this one is cottered but I'm told the chainbolt pattern & wheel is original G&J hardware, and the arms are factory set to that chainwheel setup so I'm thinking G&J must have dabbled in the same sexy curvy tech!
