I had a link to a seller on Japanese Yahoo! who was selling them, but the link is broken. So, here's a pic:
It's an umbrella cane in which, via a sliding mechanism, the umbrella furls and unfurls from inside the cane itself. I had one of American make when I was in my early 20s, but someone (me) managed to break the shaft of the cane, and no repair shop or even a metal shop could/would fix it. A friend of mine who used to live in Japan directed me to a link on Japanese Yahoo!, but the seller wouldn't ship outside of Japan.
So, who lives in Japan and is willing to buy one and sell it on to me? I've searched every flea market, yard sale, junk shop, and antique store I've visited since that fateful day when mine was destroyed, and I have never found another umbrella cane like it.
I'm going to keep this thread going until I get my hands on one!
