Seven steam locomotive replicas are going on auction in Newbury today.
The models are expected to sell for up to £200,000 at the Dreweatts and Bloomsbury Auctions.
The collection was owned by the late Don Witheridge who built his own miniature railway.
Don's model railway was fully signalled to British Rail standard which, at the time, was unique for a replica model.
Whilst working on his train project, Don was introduced to model locomotive builder John Adams.
The two men worked together as John built several skilfully crafted models for Don, many of which form the Don Witheridge collection.
