I have lately become fascinated with the Clyde Engineering ML2, B class locomotives. These locomotives were built in Australia and ran on the Australian narrow gauge railroads. Some were built, or rebuilt, with flexcoil trucks. But the original version had a truck I have yet to be able to identify. The side-frame appears to be a solid casting.
Since this is one of my “someday” projects, I would like to identify these trucks, and hopefully come up with some kind of information and maybe even specs or drawings of them. Any help would be appreciated.
