    What more do you need to know? Are you throwing it a 50th surprise party? 
    If you need gift ideas, she might like a spill switch or a rollout switch or maybe a manual reset high limit in the blower compartment. All the girls are getting them now. 
    BTW, that belt is awesome.

    Its an antique, thats why you can't get any information on it.  I've worked on a few oil fired Williamson furnaces, including the five in one. All of them were in horrible condition and a couple were unsafe to operate.  I would have an experienced professional make sure that its still safe. 

    What kind of information are you looking for?

    Made me literally laugh out loud as I was thinking nearly the same thing as soon as I saw the "-O-" in the name.

    From the look of all that dust it hasn't had a filter for a long long time. The squirrel cage assembly and evaporator assembly need to be removed and chemically cleaned, heat exchanger cleaned.................at 50 years old Not worth it!

    Start preparing for its replacement.

    Start with a Manual "J" heat load / loss calculation too find out what size is actually needed. Do Not replace like size for like size. Next have a Manual :D: duct sizing done too find out what size the ducts can handle.

    Going by looks (design) and the serial number, I guess 1971 manufacturer date.
    Is there a filter track below the blower assembly? Cant see from the pics where the return comes in.
    That's a solid door. Is there combustion air being brought into the closet somewhere? Please?

    If it's the 10x20x1 filter in the pic, then that's a disposable. It needs a new one.
    Listen to the others and start thinking about a new system. Heat and air conditioning. 
    Come back for help deciding when you're ready. There's waaay better air filters, and maybe a humidifier if needed.

    With the age of that unit I strongly advise purchasing a "Low Level" CO detector. Yes the land lord has a detector in your unit but they will not alarm until dangerous CO levels are reached and maintained.

    My preference is the Defender Model:

    Not really for sure what the chain went to an I think it's only a smoke detector

    Ask the landlord of he or she scheduled the spring A/C maintenance yet. Because no A/C means no rent.

    UL 2034 approved CO detectors will NOT alarm until 70 PPM has been reached and maintained for 60 - 180 minuets.

    The defender will begin showing levels as low as 5 PPM and alert at 15

    At the other end of the chain is a long stiff wire with a curly in the end to hold your match for lighting the pilot light.
    Especially common in older mobile homes.

    The chain has nothing attached to it unfortunately,  an the ac unit is outside but it still runs thru the furnace

    The A/C condenser is outside. Those 2 pipes running down the front of the furnace (one with the black insulation) are the refrigerant lines. They go to the evaporator coil. 
    I would check it now to make sure it works. Regardless, the landlord should have a contractor do a heat and cool maintenance twice a year. 
    It would also be a good idea to get the number off the fan belt and pick one up as a spare.
    @EdTheHeaterMan, time for your nap.
