To set the record straight, Reilly advertised Brazier locks in 1862 for an entra 5£ - a lot of money back then. Per above,
25044 was mentioned as the earliest Reilly with a Brazier action. This isn't right. There is an early extant Reilly with Brazier actions, SN
13688 - dated per the chart to 1865. Holt's did not publish a photo of the inscription.
