Graphophone AB Project

[Teak]

My new Graphophone AB is missing its metal baseplate and its mandrel fixing key. I would like to fabricate the baseplate and file down a spare original key I have. It would be very kindly appreciated if someone could provide me with measurements for the plate (l/w/h) and a tracing of the key.
If someone would have an original for sale, please let me know .

I am also looking for a spring for it and the slip-on mandrel. The spring should be same as a model B spring? Is there a seller in Europe?

your grateful
