You are probably correct in thinking that this is a special - but a special what?
The locking - apart from the combination shutter lock - is identical in outward appearance to the old List 5 which had 3 triple-stump external fantail locks - usually mastered. The body thickness was one inch and an eighth and the door one inch and a half, a sandwich with half an inch drill resisting plate in the middle.
The illustrations are of a second generation List 5, now fitted with round bolts. This was a 3-way boltwork system, as 4-way would have been thought unnecessary considering the massive ‘knuckle’ hinges.
12 Corner bent bodies came very late to Milners, with these banded models continuing until about the 1920’s I believe. The lighter safes such as the List 2 came in with 4 corner bent bodies in 1902, and 12 corner bent in 1915.
The hinges are the big mystery. Still attached to the side and in three sections like the ‘knuckle’ type. These old hinges were difficult to maintain and lubricate. Maybe non-ferrous intended for a climate prone to corrosion ? Could be vault door hinges.
No numbers visible on the body. Any elsewhere - keys maybe?
Very interesting.
