Bose 901 low serial number set (3 digit) with "patent pending" sticker

I have inherited a pair of Bose 901's that were just removed from the first time since they were installed (early 70's?)
We have tested them out and they work, but I am having a hard time trying to get a year and possible value.

The serial numbers are LOW. (#499, #452) and the sticker is typed and says "Bose Model 901 Loudspeaker Pat. #3,038,964 Pat. Pending"

Anyone have any idea where I can get info?

You need to remove the grills and look at the surrounds or edges of all the round speakers for rot or they even could be missing. If so, all the speakers need to be "re-foamed" in order to be used. If you don’t want to tackle that, they would be part units and not worth much. Also for these to work correctly, they need the equalizer that came with them when new.

The nine drivers in each speaker may have foam surrounds that tend to rot away with age. Take a look! Regarding the Bose equalizer to boost bass frequencies - throw it away! All it does is add distortion by over-driving those 4 - inch cones! Use a pair of subs crossed over at 60hz.

The original drivers in the first two versions of the 901 used cloth surrounds.
