This is my first time posting in the British/European section. A customer of mine bought this portable and had it shipped from Switzerland to the states. It was working when it left, but broken when it arrived; so he brought it to me for repairs. I had thought originally it just needed a new reproducer (I am trying to JB weld the broken on.... it’s at least worth a shot

Where is the best place to get 3 new springs for this govenor? I don’t know much about Decca machines so any help would be great. Here are some pictures of the machine for reference. I’m honestly really surprised how small it is
Is this a junior model portable?
