One of the benefits of working with Puffing Billy locomotives is the chance to discover the rich industrial heritage that come with them, such as the eccentric strap (above and below) which currently resides on 6A, and yet is clearly marked '5'.
Of the 17 NA class locomotives built, sadly only 6 still exist, and only 5 of those are currently operational. 6A, 7A, 8A, 12A and 14A are still very much alive, out every day earning their keep.
3A remains unrestored for now, but it’s time will come eventually.
This wedge, used to tighten the brass bearings in the side rods, and hold them in place, was originally part of locomotive 9A.
