Ed Dinning's your man Rob - hopefully he'll spot your post and respond.
If there's any signs of recent damp, I'd be inclined to stick it in the airing cupboard (with Angie's permission of course!) for a week or so to make sure it's well dried out. I don't think it matters if the laminations are rusty - all the iron in the core is there. As to green spot corrosion, I guess it's always a possibility, but that tends to be more of an issue with high resistance headphones, field coils of mains energised speakers, vintage inter-valve transformers, etc, all of which use very fine wire - about 48SWG. Even mains transformer primary windings tend to be thicker gauge than that.
Have fun!
