Generally, these (see attachment) are close to "N" guage, though this one is larger (approx. 1" long) and was a gift made to be a key-chain ornament for Miss Agatha (see jlaird posts in the Spridget forum). These are not "scale models", but rather miniature impressions of a particular vehicle. The Pub is actually a piece numbered #41 from Artware Studios in Congleton, England that just looked right with the car! /ubbthreads/images/graemlins/cheers.gif
PS those are "hot wheels" in the background just for a sense of scale!
