This is a vintage Harley Davidson gas tank.  I'm not sure what model or year it came off of.  We've been using it decoratively for years but it is probably still quite usable too. It does have some rust inside the tank though.  It measures " long x " wide " x "tall.  It does have some wear from age and being used but overall looks very cool.  Please see photos for condition and design and ask any questions.  Thank you.
