Sad to ear about passing of Tom Groff of the Choo Choo barn, I visited the place some years ago after York show and it was a great place to visit and enjoy.
Sometime you buy a train without knowing what it is... And I am still searching the origin of this one, a gauge one loco in British livery of the LMS. It is a Sir Gilbert Claughton class in three rail, it looks old with a nice patina and was founded with a Marklin Pacific gauge one from the twenties. Unfortunately no cars with the loco but a rake of Bing LMS cars for Basset-Lowke will look nice.
Have a nice weekend, Daniel
