Coleman condenser age

Anyone able to help me out with this one? As best I can tell, the model # is 9536A901, serial # 177000858. The whole condenser has been painted (whole other issue), but I’m pretty sure those were the numbers.

Thanks!

Numbers don’t fit my charts. Could be 1970? Could it be that old?

Could be, but I’m under the impression that the first two digits are the month if the third and fourth are the year. And while Junemberary would obviously be the 17th month of the year if it existed, I’ve yet to hear of anyone talk about a 17th month!
