KOTM,
Thank you Sir! Great info. Like you said, a little before my time also. I do remember the different serial numbers, but did not know about the St. Louis facility. Sounds like the guys who came up with the Excalibur, making a few at a time. I'd like to try that myself!! LOL!!
There was another offshoot of these guys too, the company that made "The Axe" bowling ball. It had some similarities to those old Hammers too I think.
