1939 Evinrude Mate 1/2 hp motor

So I have this old Evinrude motor and it is pretty cool. It is very tiny and in really good shape other than it is missing a couple parts. It is missing the tiller handle which I can get and it needs a coil which is the part that is difficult to find. Let me know if you have any ideas where I may find one. I am either going to keep looking for the coil or sell the motor. I know this particular motor is pretty collectible so if you have an idea what it is worth let me know. I have already had one offer for it as is.
