1933 or 1934. Check your back issues of VBQ. I think that has been covered several times - for sure in Volume 1, No. 4 on the technical trials. I do not know what the stamping was. I have seen one set of pre-war Stronglight cranks, and they looked similar to the post-war ones, just the finish-work was different.

I do not know, either. But by 1945, it appears to have been there.

My ca. 1955 Alex Singer has "no marque" stamps, and so does a 1962 Singer featured in our book "The Golden Age of Handbuilt Bicycles." However, the latter bike has many older parts that make it look like a 1952 bike...

I sometimes wonder whether they used both for a while, as I have seen quite a few earlier bikes with the "Marque." It is possible, of course, that cranks were swapped over time when owners had several bikes of different vintages.

I would call them entirely suitable.
