Old Number 679

We have been "treated" to a very cold, raw sleety day so we have not ventured too far afield. Even the garage was too cold to hold my attention for very long!
However, the old Number 679 has been around for quite a long time and needs a repair. She has somehow lost her smoke-stack and I will need to try and source a replacement - or maybe even fabricate my own. But not tonight, there's too much good stuff on the "box".
