It is a work in progress and there is still a long way to go but the major elements of the tender have been completed. The instructions have been helpful and I generally followed the sequence. However, I have left some external items to be installed when everything else is completed. A CD with prototype and construction sequence photos is included in the kit and these have been very useful during the construction.
There have been a few challenges during the construction to date. Despite the warnings in the instruction, I stuffed up the construction of the ladder. I was able to fabricate a replacement using the kit's side runners and a Uneek ladder. I also struggled with the fitting of some bronze castings.
The kit allows for the fitting of a speaker and sound decoder. I don't intend to utilise this capability but will fit pickups to all of the tender wheels and upgrade the pickups on the 50 class.
I also plan to strip back the 50 class and repaint it in conjunction with the tender. The locomotive will be renumbered as one that operated in the upper Hunter in the last years of steam. (note this paragraph has been edited to remove the inaccuracy highlighted in Phil Collin's comment below.
