Brass Train Models Picture Folio

Here we have a folio containing 14 inserts, each housing 12 pictures - mostly black and white - of beautiful brass and a few plastic train models. 168 pictures all counted. Someone has gone to great effort to document some pretty amazing looking models.
The photos look pretty old, 70's perhaps. Mostly steam with a few diesel locos and some wagons. 
Providence: This is from the estate of a relative who was an enthusiast.
