In the hopes of advancing the dialogue on dating the Stronglight 49D crank through it's unparalleled history I've uploaded a collection of photos that will hopefully illustrate most if not all of the general variants that can be seen and perhaps referenced to provide examples useful to this end.

The 49D is to me the ultimate single component spanning the on-topic era of the CR list. In terms of longevity, performance and utility, I can think of nothing that comes even remotely close. First built in the 1930s and still almost fully competitive with the most advanced current gear. If you told the people that built the first example that their design wouldn't be significantly bettered in the following 70 years, I wonder what they'd have thought?

If anyone has any photos showing variations I've missed, I'd be thrilled to add them to the collection I posted.
