Rumidor Patent #

LOOKING FOR A PATENT NUMBER regarding my model Rumidor tobacco humidor so that I can look up the year it was made. Mine says Pat. Applied for so I have no way of doing a patent search. The top of my Rumidor was damage early in its life, so when I finally managed to open the top it still had its original humidification cartridge with contents looking like as little raisin.

Can anyone provide a patent number ?

UPDATE: I believe it is U.S. patent number 1,704,908A issued in 1929 for the humidification system...?...so mine would have been made prior to 1929.

I am also interested in purchasing a damaged Rumidor so I can part it out for a good lid to fix mine.

Thanks for your time
