When did the aluminum water bottle cage come into being?

American Telephone and Telegraph.
... not to be confused with ITT, International Telephone and Telegraph...
...and not to be confused with T.A., which stands for Traction Avant. Jan Heine did a write-up on them in Bicycle Quarterly (although it might have been Vintage Bicycle Quarterly at the time). They used to make front wheel drivetrains for autos, IIRC. I've got that article in my archives somewhere.

I love anything made of aluminum. But what we really need is lighter water.

The horn was super annoying btw, and the reflector seems to go against standard Reflector Etiquette which is "white= front" and "red= rear". Maybe I should shut up... I could be swaying my victory!!!

...The band clamps and even the bolts holding the clamps shut were alloy. Nice exotic bolts that were unfortunately not very useful since (eventually) most better frames had braze-ons. I still have a little pile of those alloy bolts, can't figure out what to use them for...

I was going to mention my experience with alloy bolts. I worked in the aircraft industry, and because of one of my designs mounted in the proximity of some instruments that were sensitive to iron/steel/and the such, I mounted my item with aluminum alloy screws and nuts. The installers had such a tough time installing the screws and nuts... the threading was susceptible to galling, and then, the screws would snap. After we did some testing, I revised the design to use steel attachment hardware (which, fortunately, didn't effect the instruments). This situation bore out what I had already had come to experience with my own use of aluminum alloy fasteners on bicycles (they gall, then snap). I should have known better.
The airplane did use aluminum screws with with steel captive nuts, and I can't count how many times I had to get a drill and EZ-out because the aluminum screws had corroded and seized in that steel nuts!
I think I've got some aluminum chainring bolts on a modern bike, but there's no steel close to them, and they have loc-tite to keep the bolt from galling with the nut.

(I keep thinking we should have used anti-seize on those aluminum screws on the airplanes)

Or just rub the whole fastener assembly with water pump grease and/or bicycle grease. 👍 I was once a plumber, and among other things, I rebuilt a lot of water pumps (mostly Gould's & Jacuzzis). I put grease on everything, especially the impellor shaft & hardware. It makes a huge difference, as a rust inhibitor. 🙂

While aluminum bottles and handlebar mounts were made by Coloral, the only downtube holders they made I have seen were steel, not aluminum. I think the OP is looking for the ubiquitous design in steelbikeguy's post.
