Mitchell 3390

[Donnyboat]

I managed to get this reel @ n/c, on an old rod, has a lot of corrosion on the rotor & spool, but to my surprise, it turns very smooth, but I need some info of it, it has a manual pick up arm, also on the other side of the rotor, it has a switch of some kind, with a rubber cover, I would like more info before, I tear it apart, also some schematics would be handy, thanks in advance, cheers Don.
