K&R, I like blenders even though I don't use one all that regularly. I thinned my small collection when we moved a couple of years ago, but hung onto my '40s Waring "rocket ship" to use at the bar, which always elicits compliments, my '60s Sears/Oster with sliding speed control (thanks, Nate!), and my Oster Cycla-trol, which has timer issues that I'm determined to resolve when I feel like devoting the time to doing so.
I'm always on the lookout for vintage glass carafes for these machines and have a stash of spares.
Vintage blenders are so much quieter in their operation compared to today's models, and the "fusion" blade on my Sears/Oster gives it nearly the same level of capability as the expensive Brevilles currently on the market.
Thanks for sharing some examples from your collection with us!
