Smith and Egge made this brass lock for the New York New Haven & Hartford Railroad. It has "THE S&E M Co" hallmark on the shackle. There are "A" and "Q" stamped on the shackle. Outside of Quincy, Massachusetts I can't come up with any "Q" thoughts on the New Haven. There are some rim dings. The dust cover is sprung and so is the shackle.
