Alan Treherne designated the various Massey escapements numbers in the order he identified them. They are not an indication of which came first. Over the years it has become clear that the steel roller, type-1, was the earliest to be used, apart that is, from the very first form shown in his 1812 Patent application. At some point around 1820 Massey started to offer jewelled rollers, the type-5 being the earliest. This was followed by the type-2 roller, which itself was soon followed by type-3, the most common.
In generally good condition but noting wear to the case, the balance-brake not operational (as usual), the dial with hair cracks and lacking the tip of the minute hand. Not serviced by me, and nothing broken, but will not continue to tick when wound. Sold as needing at least a service and fresh oil to work properly – priced accordingly.
