Not exactly a huge hoard, but...
Four vintage KitchenAid food processors, made in Fance and heavier than a tank.
Cookbooks, vintage gardening books, history books.
Electric percolators (I have ten and use them according to my mood)
Russell Hobbs electric kettles, the traditional ones. One is in daily use and four are stored away for when this one goes belly-up.
Libbey Tawny Accent glasses - footed and unfooted.
I used to be over run with vacuum cleaners and Western Electric rotary dial telephones. Pared the vacuums beck to a small collection of what I like to use, and sold the phones on eBay, only keeping the three that are in use, here at the house.
Oh, I had a hoard of Panasonic dual cassette answering machines, too, but unloaded them on eBay before I moved from the city and went with a little digital gizmo.
