The Trunion Plates
These steel Trunion Plates will be bolted around the Cheeks. The Barrel trunions will mount onto the Carriage at this point.
As can be seen on the six pounder drawings, there is a quantity of
trail metal work furniture to be produced. These pieces aide in the manoeuvring of the carriage
or are required to hold the various cannon operating implements.
Clockwise from far left:
Wheel washers, Hook washer, Cleate (for rope), Trail Bolt with Chain Bracket,
