Phil, one good thing about these is that they are very compact with the front panel closed and they can fit in a relatively small box. So if you find one and it's not local, it's not very expensive to ship!
I got other hoods while visiting houses with appliances for sale (I got one along with my 1964 Filtrator dryer, another one with one of my A806 washers and a few more when buying ovens/cooktops). The largest one I got is a stainless steel 48" Nutone V50 and I bought that one on eBay. That one was a bit more expensive to ship... I still haven't used it but I hope to use it someday!
Here's one Nutone V50 featured in another French-Canadian ad <span style="font-size: 12pt;">(strangely, it's installed over a regular 30" range) </span><span style="font-size: 12pt;">so you can see how big it is! The one in the ad is missing it's original knobs but mine still has them. This strange kitchen seems to have a Tappan-Gurney Visualite double wall oven at the opposite side of the kitchen. I can't tell if this ad was done in a real house or staged but in either way, I wondering how they came with an idea like that! Maybe the house originally had one large cooktop that was later replaced with a free-standing range. If the cooktop was also a Tappan, no wonder why they replaced it with a free standing range in the early eighties! Tappan built-ins were quite popular in Québec but they weren't too good and generally survived by their matching ovens (which were, in most cases, not used as much I guess).</span>
And here's my V-50 hood (the first picture shows it where it was originally installed (in Michigan if I remember well). <span style="font-size: 12pt;"> </span><span style="font-size: 12pt;">This one has two speeds but unlike the other ones with a variable speed single motor, this one has just one motor turning at full speed on "low", and on the "hi" setting, both blowers turn. That's why the knob has "Blowers" instead of "Blower" written on it.</span>
