Oh man, i am embarrassed - somehow i did a typo in stating the length of the Tank!
It is 25 inches long, counting the Seam.
( Not 35 inches long ).
So, "Half Ton" tank I would expect...( rather than a 1 Ton Tank ).
So, should have read -
If counting the seam - 25 inches long.
If counting the seam - 14 inches deep/wide.
12-5/8ths inches tall.
