Hi Barney, I cant help with what you want but just a heads up about issues you might run into with this.
You should be able to find someone to make the spindles but you will probably need patterns; I'm sure Andy at Kingpin would be able to do it but he's more into Nortons and I doubt he'd know the dimensions which may  explain why you haven't heard back yet.
The material most people use is EN16T steel - worth checking that because not every engineer understands the specific requirements for bikes and it needs to be the right stuff. Also I'm no sure those forks have bushes - my 1932 'dogleg' forks don't but not sure what's fitted for 1936. If as on earlier types they run direct in the metal of the fork, it may be possible to get the forks bored out and bushes made/fitted but that's a specialist job and not always possible because if the material is not very thick it could be weakened by boring out the hole. In that case it may be possible to just get the holes honed to  take out the wear and have oversize spindles made to match - but again that's a specialist job. On the other hand, you may find that new standard spindles take out enough of the wear to live with.
Hope this helps and good luck with it
Cheers Rick
