Yes it's the brickyard museum - http://chemin-fer-baie-saint-brieuc.fr
I'm glad you all appreciate it - it was my first day out after having been down with flu for a week. Got myself soaked doing it and woke up with a cold this morning! The sacrifices we make for the hobby....
Must admit they were smaller than even I remember. I thought the wheels were the same as the 10 inch ones we used at Windmill Farm, but they were a little under 20 cm so around 8 inch. The axle were 40mm in diameter and the bearing surface in the journal at the end only 20mm in diameter.
Overall they are only about half the size of the Theakston on the Ravenglass.
