I swapped some products and got one from a Glass Company's Purchasing Agent years ago. It was a special edition and was nickle plated for show. Obviously it is an Iron Casting, weighs a ton. It's a Jack Daniels Bottle.
Can not find anything on two-finger handle bottles. Has: DES PAT 87834 in glass and a manufacturers mark of a "O" with a capital I in it, the 0 Symbol has two "V"s sticking straight out off sides at the 9 and 3 O'Clock positions. I'm guessing that the Manufacturer was Owns Illinois from the OI...
Found it, the name in raised print is DUROGLAS I think it's a Gallon Capacity. I can not find anything on it has a metal bucket type style handle. Looks like a MoonShine Bottle..
