His name and address are:
John Callaghan
PO Box 82
Southhampton, MA 01073

I got his name from Savage Customer service.
I wrote him a nice letter, told him where I got his name and address, gave him as much information about the rifle as I could, and told him that I really appreciated the service he provided. I threw in a few extra stamps for good measure.
He got back to me a couple of weeks later with an approximate manufacturing date.
Good luck.
