Vintage Oil Gas Water Barrel float and gauge MH 2119 Brass/ coper floats

Description

For sale is a "MH 2119" gauge and floats mechanism. Likely once attached to an oil/ gas/ water/ something barrel.  Untested and selling mostly as is. Has rust and dirty spots, scuffs, scrapes. Float has a dent. Would float in a full barrel and as it empties the floats pull down on the spring and moves towards the E...May be best for another use.
The main gauge part is made of metal and about 4 7/8" long with screw end around 1 3/4" across.  Has intact glass viewer with spring inside to mark "E 1/4 1/2 3/4 F".  Does move up and down but unsure of the accuracy.  Spring attached to a wire that has loops attached to the 5 brass/ copper floats.  Each float is about 4 1/2" x 1 1/4" x 1".  Third in line is dented.
Please refer to the pictures and contact me if you have any questions.
After the sale I will leave feedback soon after you.
