Thank you for all the info and suggestions...I was able to find the serial number (it was born in 1961) and clean the case. The case cleaned up beautifully and the plastic is in pretty good shape for it's age. I think if I end up using it much that I'll try to find a wooden base to put it in. I am going to try to post a picture but haven't done that before so I apologize in advance if it doesn't work.
