Looks like your bottle was stamped by the State Of Illinois between 1949-1952. (Your missing # under the split is either a 1 or a 2; most likely a 1).
This is a god bottle, getting a bit rough on the labels, so I would suggest not handling it much (definately try not to lay it on it's side, as the high alcohol content will consume the cork).
NOt sure what your fill-level looks like, but this should be worth between $150-$200 US, and is a good whisky for drinking!
