Thanks for the tip.
Will try that within a day or two.
Is there not a special tool that one can use instead of a screwdriver?
Will try to salvage the chain, but I have doubts about this one. If a new single gear chain is not long enough, I guess I can always buy two and add a piece of one to the other.
I will look for the name of the bearings in the crank and let you know. I think that I saw sonething like hartford on the bearing sets in the rear wheel hub.

I wouldnt paint the saddle springs, just soak em in oil, the springs were probably chrome tho, Dont be afraid of rust... Im sure you can still use the original chain if you soak it over night in oil or kerosene.
You might be able to buy a replacement chain if you want I guess (i forget the "size"), but it will be labeled for single speed bikes, dont get one for a derailer bike it wont work. Hope its long enough though, thats a 28" bike with a pretty large front sprocket, most single speed chains today are sold for BMXs.. so I would really advice you try to use the original chain if you could.
If that doesnt work you can try to find another old 28" single speed bike as a donor and use its chain.. if you dont know where to find one I would suggest the dump.. or post a want ad looking for old rusty single speed bike, im sure you can buy one cheap enough. You might need a mens model as girls model bikes usually had smaller sprockets which means a shorter chain.
PS: do the bearings in the crank say "Hartford USA 64" on them? I just ask as every crank set bearings ive seen so far have been that type, from my oldest bikes to some little kids bikes ive taken apart. (same size crank housings!)
