The Wilesco D21 as it arrived.
I spent an hour the other day disassembling the engine into it's component parts. I soldered the boiler bushes back into the boiler and all seems to be sound there. Upon disassembly I noticed the paint was in slightly worse condition than I initially thought so I decided that I had may as well repaint it before putting it together. I don't like painting. Which means this project will probably take longer than planned! Here it is after disassembly, but prior to the removal of some of the paint.
