This bat is labeled as being a '56-'59 era bat:

But be aware if you have bid or may bid, this is actually a 1960 specific bat based on the labeling. I believe a decent portion of value leaves then because the late 50s for Milwaukee covers two WS years and their big WS winning year. The 50s bats are also generally tougher to find as well.
