What I found is that it was a C-mount lens designed for 1/2 inch video tubes? That would then be for a recording area of about 6.4x4.8mm. 11 Size

 

In that usage it would then be equivalent to a 67.5mm lens on 135 format (not taking into account the different aspect ratios). For 16mm film it would then be equivalent to a 35mm lens on 135 format.

 

I believe the 1st commercial lens for photography with an aspherical element was the Canon FD 55mm f1.2 Aspherical. This lens still has a cult following keeping prices pretty high still.

It does much better wide open/close up than my FL 55mm f1.2, but its bokeh is not a real winner (depending on the distance).
