Thats a hand and a half sword, I was able to study a period one from the mid 1500's last week. The one I handled was a double ring guard though, blade profile would be the same. If you want I can check on the dimensions and pics I have.

I have some of burton's 5160 stock. Are you forging or doing stock removal? these pieces are like, 48 inches long and .23ish thick, 1.5 inches wide IIRC. I could go outside and check.
