Age help Bryant

Need help with the age of a Bryant Ser#47M29305 Model #100 393USB

Thanks for any help!

Hi Steve,

I can’t be sure about this as Prtestons’ doesn’t list that specific model #, however it is the style of model number that they used in the late 1960’s up to the early 1970’s.



Thanks Gerry, There was a part number of 54056 CO 2. Would that be anything that would help indicate the year?
