Chatwood "SAM" ???? or copy

[macs_07]

This combination lock is very similar to the Chatwood "SAM" lock but it is not numbered or stamped. It has a small triangle and star in the position two sections to the left of the 'A'. The major parts of the lock are stamped with a '1' but I believe this is just to identify them as part of this lock set and as such has not been made from multiple locks and is original.
Very heavy and predominantly all brass in construction.
The body is 100 wide X 50 deep X 139 high.
