I'm far from an expert on this subject but I do know this.  Powder
extinguishers like the one that comes 'issue' in a Westy will pack down over
time, just sitting in a rack on the wall.  The industry apparently refers to
this as 'bricking up', at least that's the term I ran into today on a
website for an extinguisher vendor.  And I'd expect that the vibration in a
vehicle would make this even worse, just perfect to settle the powder.  (If
anyone has info to the contrary that would be great to hear).  What many
have done is take the original unit and store it for use in future
restoration and replace it with a newer unit.  And as far as I can remember
the OEM extinguisher does not have a gauge on it to tell you if it still has
pressure and I don't think they can be refilled.  I could be wrong on that,
mine is buried down in my storage unit and I'm not going to go down to
check.  I'm carrying a Halon extinguisher.
