Just a quick note to share info and...to brag a bit... Found a Hoover 725 for one dollar at a garage sale in working condition. Cleaned it up, and looks like it just rolled off the assembly line in 1931. Works perfectly, all parts like new including the bag, and a great addition to my 541, vintage salmon-pink flower-power Convertible, Constellation 86, and a Persian gold Dial-a-Matic... Found two great vintage Hoovers in two weeks, so watch those garage sales in the summer !
I got a pair of 725's plus an original dusting tool set in original box last year. One of the 725's is in good shape, and the other needs a heavy duty rehab. It has interesting differences between it and the 700.
