WANTED: Orthophonic dynamic driver or dimensions

[broso252]

I'm looking for the victor dynamic horn driver used on the victor 10-51 (sometimes also found on the 9-40 and 8-60) so that I can model and test replacement parts for the pot metal that is often warped or damaged.
If no one would like to give up their dynamic driver, would anyone be interested in taking apart and giving dimensions of their driver and testing the resultant parts?
The first prototypes will likely be 3D printed to test fit and function. Once we have a working part, the model should be able to be cast or milled in metal. (would aluminum be best?)
Attached to this post should be an image of a proof of concept model I have made and the picture it was based on.
Thanks

A very interesting project indeed!
