If the unit still has the serial number sticker, sometimes it says if it's
R12 refrigerant, or R134a. They changed over about 1994 or 1995. Might be
some help.

My Coldspot/Sears upright freezer is dying. I am trying to figure out
how long we have had it. 30+ years is my wife's guess. Model is
106.628440. The original parts list does not have a date and we can't
find any sales slip or other info. Any idea how to tell about how
old it is?
