[VAC] Re: I have 5 large numbers which were removed on my airstream, what do they signify?

[Dale Lee <dl@xxxxxxxxxxxxxxxx>]

Hi Streamers,  I think I have a very stupid or very obvious question which I
seek an answer.  Very curious about what the removed numbers are above the
front of my recently acquired airstream.  The numbers were situated above the
airstream name placard on the upper front above the glass window.  The numbers
are 18927 , I think.  I was searching in the cabinets and discovered the
original warranty, this trailer was sold new to a person in San Diego, CA in
june, 1967.  Its a 17' caravel.  Any input would be appreciated...  Thanks so
much,  Dale
