Lucas Condensor shelf life

[Malcolm Walker <walker05@camosun.bc.ca>]

I just found a NOS Lucas condensor that has been sitting on a shelf in my
workshop for many, many years.  The most recent date on the backside is
1971- so I imagine it's circa '75 or so.  Do these things go bad from
sitting?

The package (card) says it's a C1, aka 423871.  Fits all sorts of british
cars- was probably bought for the Cortina we were cursed with some time
ago.
