This actually started on this thread but I think it's worth hoisting to the top (for a couple of reasons!).

Many thanks Fugolman for IDing these as Chandler Robbins' bins.
That's Chandler S. "Golden Guide" Robbins for those that forgot. Like me. Not that I'll forget again! And the Breeding Bird Survey. And Breeding Bird Atlas. Yikes! Amongst others.

There are quite a few pics in various states in the Gallery where the leather armor stands out. And you can clearly see that these are the same bins (with the "field marks" on the end of the left barrel being diagnostic!).

The photo, taken by Laura Erickson, is in Flicker too in the original size too and the meium I've attached to this post.

Anyone care to ID the bins?
Laura Erickson took this photo on February 17, 2007 and helpfully placed the original photo on Flickr. High resolution is very useful. It shows some lettering around the inside of the barrels. Pushing the exposure in an image viewer and I can read most of them.
The right barrel has " X 50mm" and "7° 10'" (I think) and "FULLY COATED". I think the magnification is "10 X 50mm". It's certainly two characters.
The mangled left barrel appears to have "BUSHNELL" and "...TED" which I presume is "COATED" also. So just those mangled letters after bushnell remain unidentified.
So a fullly coated Bushnell 10x50mm porro. With quite a wide field for a 10x at more than 7 degrees (you won't see that today ... 6.8° seems to be the largest FOV one can find and that only in the "Top Four"). From the 1960s? 1970s?
Any model ID?
The closet descendent I can find is the non-waterproof Bushnell Bausch & Lomb 10x50 Legacy Wide Angle Porro Prism Binocular with 7.2° FOV and 9mm ER. No longer sold (and replaced by a more ordinary waterproof Legacy WP). I presume harking back to even earlier Bushnell wide angle porros.
The leather armor I presume is an aftermarket addition.
Clearly an expert birder using a wide angle 10x bin. Now that's "old school"

Actually those bins belong to the notable birder Chandler Robbins and are supposedly still in use. Methinks I would have retired them but who knows. . .they could be his lucky bins. ||

I think in the above pic those may be the same bins with the leather wrapping intact.
