I've decided my Marconi 702 needs a new mirror. It appears to
be 14x22 inches, at least very close.

It would be best to get a front surface one. I had trouble finding
somebody to sell me one. I finally did, in acrylic, for $192.

Has anybody else found one cheaper, acrylic or glass?

I've been unable to find a second surface one that is either thin enough
(<1/16 inch) or antireflection coated.

Has anybody found one?

Total crapshoot, but look for mid-90s to early 2000s projection sets. I found a fairly large front surface mirror suitable for use in my UST projection set for far less than I would have spent buying from the limited commercial options.

200% agreement. I parted out some sets from curbside, I have now to learn how
to cut the glass.
You only have to break the front plastic and you can screw off the mirror. They are always made of real glass.

Thanks! But no thanks ... such sets are impossible to find around here
due to state regulations.

You could try talking to a recycling center or 2. They would get those projection sets and probably don't make anything off the mirror so you might be able to talk them into selling the mirror to you. It would be less hastle than trying to find one on the curb (or out here one dumped in a field), and you wouldn't end up saddled with the whole set.
