This is a very common filter. They have been made by hundreds of different
manufacturers over the years world wide. The size of the filter determines
more than anything else, the pressure drop across the unit and the argument
is the bigger the better. Filters can operate in 2 modes, full flow or
bypass flow. This particular filter is clearly a bypass flow device because
of the small fitting size, so these do NOT work in all applications.

what follows is something of a shaggy dog story, a link to ebay, and a
question - with that warning, read or ignore as you see fit. The object
in question is made of steel, so the mandatory metal content is satisfied,
and I even had to use an extractor to remove a piece I broke, so there is
some minor metal working content too.

About 20 years ago (plus or minus a few), at a swap meet I bought an
external canister oil filter thinking I might use it on a 36 cadillac I
had started restoring (by the way, the car still isn't done - but that
probably doesn't surprise anyone - there's a photo or two on my web page,
wbnoble.com). The filter came in a burlap bag, and when I decided that it
wasn't sufficiently original for my tastes, I hung it from the rafters of
my garage and pretty much forgot about it. Yesterday I looked up and
noticed that the burlap was starting to tear, so I took it down, wiped the
dust off it and put it on ebay - if I haven't used it in 20 years, the
theory goes, then I probably don't need it - but in the process of making
up the listing, I did a bunch of searching, found a catalog that listed it
(all these things are in the auction, here
http://cgi.ebay.com/ws/eBayISAPI.dll...m=300226458615
and I read the catalog description. This is a very large filter, but they
say it is for cars (!) with a crank case capacity of up to 6 quarts - so
that would be typical of most cars up through the 70s - 5 quarts being a
pretty common capacity. The filter itself holds 3 quarts - and it's
really quite big - bigger even than the ones that used toilet paper as the
filter medium.

So my question is were these things REALLY used on cars or was this more
for a truck or tractor application - somehow I just can't imagine it on a
regular passanger car - maybe they were used on taxis? Anyone on this
group remember these things and their usage? It's not at all clear what
makes them so special, to me it looks just like a giant canister oil
filter - am I missing something?
