Quoting from Reilly (American Socket Bayonets and Scabbards), "the bayonet for the US Musket, Model 1816...is nominally 19 inches overall, with a 3 inch socket, a 16x 15/16 inch blade and a bore diameter of approximately .826-.830 inches." There is a known list of initials of inspectors of 1816 bayonets. "RJ" is one of those listed.
If heavily rusted, my .02 is that I would clean off the surface rust. I'd soak it in Kroil or some other penetrating oil for a couple of days. That alone will lift some of the rust. Then I'd clean with what are called "kettle cleaners", this is what they look like:

I use Kroil and the kettle cleaner to get off the remaining rust (heck, all it's gonna do is attrack moisture and create even more rust). NOTE: These cleaning pads WILL NOT destroy the underlying patina. Then, depending on the climate you live in and will display the item, I'd use a product called Renaissance Wax to preserve the piece and prevent further deterioration. The stuff isn't cheap, but it goes a long way. The WWII museum in New Orleans uses it to preserve artifacts - and they aren't known as a "dry" climate! HTH
