The chassis is pretty bad, the eccentrics straps are loose, the lifting arms have the most play and on one side the lifting arm can be taken off without any disassembly. The piston rod guides were loose and subsequently there is also play in those, worse so on the right side.

Once they were stripped down the the chassis, I checked the top side on a flat surface, there was excessive rock in the frames, (2-3mm) on a flat surface, so unfortunately this meant further dismantling, to make sure there was a solid register surface to work to, which would enable the squaring up of the frames once ready. While I was at stripping it, I also filed the raised rivet heads around the hornblocks on the chassis, this means they can't interfere with the wheels and run, so these were filed flat. Also the derailing forks leading and training the wheels had the raised heads of the rivets filed off so they could be accurately drilled and removed to check the lower edge for a register

Worringly considering frames should be made as a parralel set the holes for the smokebox don't seem to have been drilled at the same time, and are out of alignment. Hopefully this is the only one that is out of alignment.
