Thermostat

I recently located a thermostat that was new in the box but it
had expanded, I assume, because the seal had failed somewhere.
It doesn't have any physical damage and no visible cracks in
the diaphram. I was thinking that maybe the solder on either the
top or bottom was weak. Has anyone ever repaired one of these?
I assume that it must have had a vacuum of some sort in it in
order to help keep it compressed.

Vacuum, and some fairly volatile, easily evaporating alcohol inside. I
don't know what, or how much of it. Once it's gone, you can't fix it at
home.

That's what I was afraid of. It's a fairly simple device. I'd like to see
how it was done.
