Carl,

The rubber covered jettison tank is the old type and holds 25 gallons.
This type was used on the Stuart and on early Staghounds.
On the Staghound, this type was also used for a short period without the rubber covering.
In this case, wooden blocks were mounted on the tank supports to compensate for the smaller radius oof these tanks.

The latest type used on the Staghound is all steel, it has the same outer dimensions as the old type and holds 37 gallons.
I do not know if these were used on the Stuart also.

I really wouldn't know were to find these tanks.
The tank on the photo is the only survivor of the rubber type I have ever seen.
I can sent you photo's and dimensions from the 37 gallon tank and the straps which hold the tank if you are interested.
