Any suggestions short of cutting the case in two G would be
appreciated.

Thanks, Dick

Look at the back of the case for screws. The innards are mounted to the
back of the case.

Dan, can it be opened without destroying the instrument?

I have a Garwin, Inc. altimiter. Serial number 721, dated Mar 29 1962.
It's in working condition, and I'd like it to stay that way. It has
a little crust on the inside of the front glass. Not enough for me to
pay someone to clean it, but I'd like to run a damp cloth across it if I
could get to it.

decisions, but in doing so we actually hurt them (and ourselves)."
