Agree with Cycleops about the wheels, the stem looks very much like a GB "girder" stem that I have although no GB markings on it by the look of things (I think a GB girder would get you your money back on
eBay).
I would clean the drop bars and after inspection either wrap cloth tape right up to the stem or replace;

I think that the chain may also need replacing
Thanks for putting up the photos
