The coke machine my neighbor gave me!

Hi! A few months ago my elderly neighbor passed away and her daughter asked me if i could help her clean up the place. I said yes and got to work. For payment since i didn't want to take any of her money, i asked if i could have any tools or things that i thought were of use to me and she said i could have it all. Well in the basement i found this old Coca Cola machine and now i'm wondering what it might be worth? I've looked up the model number and it's made by Ideal and it's a model A-55 apparently from the 40's or 50's? If someone could please tell me about it i'd really appreciate it! I plugged it it and it still works and get's cold pretty quick. I think it's missing the change machine part of it and something else i'm not sure. Any help here would be much appreciated!
Thank you!!
