Milner is the topic of our first research venture for this cluster of sites. As Milner is a English company the thread is located on the HoL forum HERE. The leter date codes are HERE. The Milner research project is one that’s long overdue in that there is so much detail that can be assimilated in the form of numbers marks, symbols and lock variations. Any member of Antique Locks that would like to be added to the HoL forum with your existing login simply email Merlin 47 with your details. Hopefully everybody can add their Milner locks to the HoL thread.
