If your buying the pin with the intention of fixing it then selling for a profit forget it. Buying EM's and making money in general is a tough deal.
I never buy a pin with the intention of fixing it and making money from it but rather saving these things from extinction so others may enjoy them in the future.
If you are not into doing the restoration then please pass it along to someone who will. As others have stated, all parts you mentioned are available for that machine.
