Francisco ARIZMENDI
The cross in a surmounted blazon of a crown: punch of the proofhouse of Eibar since 1923 until the 9.7.1931.
Late manufacture (for this type of weapon): the letter B indicates that the weapon was tested in 1928.
FA crescent : tt’s the mark of Francisco ARIZMENDI, of Eibar.
It liked much the crescent (?) in its trademarks…
