[SEL] Drip Oiler Needed - Port Hole - Nathan - Austral

[Rob Skinner]

G'day mates,
I'm looking for a port hole oiler as would be found on an
early Austral.  The goal is to get two 2.5" oilers that I
think are correct for the engine, or a 3" to match the one
in the following picture.  
 
I'm measuring the extreme outside diameter of the brass.
The glass is about 0.25" smaller in diameter.  
 
Although it goes on an Australian engine, I've been told the
manufacturer is American.  Perhaps it was Nathan.  
 
A picture of an oiler that has been chopped up and modified
can be seen here:

Thanks for looking through your parts bins,
Rob
