Help with an antique stove....
 

Hoping to find some help with the old stove that I'm considering buying. Its a Tappan Model D-19 - probably early 50s. I haven't bought it and have two concerns/questions.
1. Its missing the cover on the light, as seen in the photos - any idea where I can find one?
2. It has a chip in the procelain that concerns me - can these be repaired without re doing the whole thing?

Thanks
Lane
