The Old chap who built these models about 50 years ago was very good at construction - although painting has improved a long way in recent years.

These items are available for sale and appear to be the 3/16th scale imperial form of the gauge and are 3 rail stud contact. An intriguing scale that I hadn't encountered before.

It would be good for these nice locos to go to a new home with an 'S' gauge modeller who would appreciate them.
