Old Gas Container

This is a fun find. 

From what I can figure out and what I have been told by a few, this is a Gasoline Container. 

It is about three feet tall and about eleven inches, (at the widest point) in diameter.  Rock had this in his yard among all his colorful flowers.  This may be the reason for it's weatherd condition. 

It is a Seraphin Model es-5d.  15 gallon capacity.

It was used for "quick fill" maybe in car races.

Knowing Rock's love for cars, this is probably something he found during one of his shopping sprees at antiques shops across the country, he had to have and probably knew exactly where it was going to sit.
