Nice tank to a ball hopper Monitor. Im not sure how many sizes of the monitor this tank fits but Ill do my best at providing measurements. Very solid and original cast iron tank! Definitely a really rare piece especially if youre looking for one! Threads might need cleaned up a bit and the mouse nest inside needs taken out. Would look great on a engine or shelf! From end to end the tank measure 15.75. Tank is 7 in diameter. From outside to outside of the mounting ears, measures 8 3/8.
