I notice that Chater Lea chainsets come in several varieties, some of which have been discussed in the past. I recently acquired a very nice CL chainset thanks to Martin Coopland that has the oh so elegant two prong configuration with the third attachment point on the chank arm. I see that CL cranks also came in a three prong configuration.
Can someone tell me if these models were made concurrently? If not, which is earlier? Which was more common? Were they for different applications?
I strongly prefer the 2 prong arrangement myself.
