Westinghouse dd144 coke machine

i recently bought a westinghouse coke machine, possibly 1950's. i can't find any other like it anywhere. i am in need of some info for restoration.
it's an upright, side door to take out the soda, and has a capacity of 144. the tag says dd144 westinghouse.
coca cola is embossed in the machine, but someone covered it to make a pepsi machine. this is for home use, nit resale, but i want it to look as authenic as possible. any suggestions?
