Hi Bruce,
Just went through the entire thread, in an attempt to get the "full picture" here
Already have commented on the stationary engines, but i really like the mobiles and their mods too.
Some of them even rebuilt pretty extensively, but all changes appear well pondered and very nicely executed.
Well done & thanks for sharing!
PS:
...and thanks for the the final movie, with the trio of traction engines, it just made me realise how stupid i was to let (almost) my entire Wilesco collection go.
Will definitely not be going for a complete collection again, but there is certainly a handful which will be added here again, including an older D40.
