19th Century East India British Trading Company Flintlock ID?

[Berkley]

While better photos would be helpful, I believe based on what is shown that the lock is not an original Birmingham-made East India Company lock, but rather a Khyber Pass copy. The lockplate is made of flat stock, rather than having the gracefully rounded edges of an original. The date is stamped with poorly spaced numerals in a modern sans serif font. The protruding screw heads of the internal lock mechanism are nothing like the smoothly finished originals.
