I found your blog by accident, and I'm just catching up on your entries now. I'm not an N gauge modeller or an LMS fan but your blogs are turning into vital reading for me, you really are a talented modeller.
The LNER teaks look great, some of the weathering is very subtle, I remember teaks, in BR days being in a terrible state, so maybe you should apply more "grot". The only complaint I have so far is that you need to do more of a step by step entry so modellers like me can learn your secrets.
Just out of interest I have an 0 gauge rake you can weather, purely so that other modellers can learn how to do it?
