Hoover 63
Hi Joe,
I'm not sure what info you're looking for, but Hoover built over 4 million 63's from 1953 to 1956. It was the first Hoover to use the type C disposable bag, which was also used for the Convertible.
If you're looking to put a date on your 63, the serial numbers ran from A-1,130,001 to A-5,457,313. Look at your serial number, and if it's close to the lower number, it was probably built in 1953, if close to the higher number it would be 1956, and in between could be 54 or 55.
Hope this helps,
Jeff
