[dsg-hallb_rich] [EXTERNAL] Re: Place to move spare Hall B RICH planar mirrors for long term storage?

[Walt Akers]

Hey Tyler:

I'm out of the office today, but will be back tomorrow.  Without
knowing the size of the mirrors, I would suspect that if they
will fit on a shelf, they might best be stored in the ESB.

Check with Denny Insley to see if he has any spare space on
his shelves in the ESB.
