People all use hand held blower vacs these days. I think VVs came out before. They are only designed to be used on pathways I believe plus they have to be plugged in, so are not very versatile compared to B/V hands helds.
Victa pumped out loads of the things so I don't imagine they would be of any value to a collector. Those wheels would be in near new condition to fit onto a mower.
Another opinion or two would be of help. Maybe these had exceptional power and ability. I remember a man from across the street got himself a fancy toy in the form of a new b/v and it couldn't handle those spikey seed balls that fall off a maple tree that clogged the machine.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
