Is that a Silver Streak? It looks rough, but if it's still as solid as it looks, no major floor repair or leak damage you might be further ahead by selling it as is. To part it out you're going to have to prove every appliance operates. Larger items will have to go freight which means pallets and packaging headaches. You're going to run into a lot of jerks who screw with you wanting money back because they didn't do their homework, or claim what you sent didn't work or as listed.
If it's a Silver Streak you know they're pretty desirable, if it's complete except for the items you took they're easily replaceable with modern equivalents if the buyer isn't a purist. If you get what you paid for it you got the AC and water tank and compressor for free, and don't have to deal with all the headaches of selling used parts.
