A. Model Triple C, (later no. 6306), made 1889. This model differed from the A and B designs as it used a side bolt-engagement extension to hook into the bolt work thus there is no dog within the case to block the bolt work. It also incorporated a larger movement than the 'L' size used in the triple B. The larger movement was called the 'M' size and was the largest the company made. These were introduced with the advent of very large vault doors requiring ever stronger release power. Only 150 of these were originally made making this the rarest of the Triple A, B and C designs. These were made almost exclusively for the Damon Safe Company of Boston until 1914, after which the balance were delivered to York Safe & Lock Company of York, Pennsylvania. (1) This example was very early in this design series. The case is slightly larger than the later production models and features a half glass door with winding holes in the metal section. This is the only S&G I've seen using this type of door. All of their other locks have full glass with or without provision for winding holes. The case and movements have very early serial numbers. The configuration of the snubber bar pivots are differently configured. An interior shot of the door shows a good example of the spotted jeweling pattern S&G used for most of their bronze cases. This could have been an early prototype making this the earliest Model C known and the only known example of this variation.
