    London/Birmingham proof marks

    The table below can be used to see if your gun was proofed in London or Birmingham. Many old guns may have been re-proved once or more, often in a different proof house from the original one.

    By seeking the marks listed in the table, the latest a gun could have been proved originally can be established, as can the time frame of any re-proof that may have been applied later in the gun’s life.
