All,

I have been looking for quite some years for a replacement back plate for my one group 1st generation Urania. The attached picture shows the two group version of the plate, I am looking for the one group version of it. I know - unobtanium!!! Maybe someone here has an idea of how to make a copy of that plate (3D printing, vacuum forming, etc), any advice is highly appreciated.

Thank you so much!
