Well, I posted my photo of this in another thread recently, but there have been some interesting developments, and I think this mystery deserves its own thread now.
In a nutshell: Once upon a time I was just out driving around all day. With no purpose other than to explore. I happened to go behind another building somewhere in Western Mass, and noticed what I thought must be an abandoned B&M Depot. I got my camera, took a picture, and went on my way, not giving it any more thought.
Until a few years ago when I came across the photo. At that time I added it to my website about Mass and NH Mystery Depots. Recently I have learned a lot more, and just updated my page. I welcome any info you might have.
Here is the page.....

I was going to add, "Thanks to Buddy W, and to Alden". And I was going to e-mail Buddy to tell him I added his photos. But when I logged in today, I noticed Buddy posted a new thread yesterday. So I'll wait and let him see this and be surprized.
