This a NOS, new old stock 2 1/2 gallon gas tank for a Jacobsen lawn mower or other engine.  It is in great, unused condition with handling wear and age oxidation as can be seen but still has vibrant color and graphics.  It has the original screened spout in it.  It measures about 6 x 15 x 10 inches tall.  It has a few minor dings from over the years.  The inside is shiny and like new.  This would be great addition to your early Jacobsen collection or display.  The pictures tell the story.  I don't think theres many of these left to be found in the wild anymore so don't miss it.  I can be reached at: 262 573 193 1 if you'd like to talk about it.  Good Luck.
