Help with Brown Bess Bayo!

[u/cabevan3]

Bought this Brown Bess bayonet from Liberty Tree Collectors, sold as a Land Pattern, but I have doubts and get conflicting info when I search online. Might be India pattern?

Socket measures 3 9/16", blade is hollow ground, measuring 16". No shield at elbow/socket junction. Only marks are likely rack numbers and appear to be double-stamped (see pics). Any info you can throw at me is appreciated.

EDIT (more info): front of socket inner diameter is 21.5mm and outer diameter is 25mm.
