Shop Stock Room Find. Discovered in the store room of a closing down shop along with many other old and vintage items. May have been used as a display model at some point which is most likely why it was never sold, but all items appear to be present with the instructions printed on the back of the box. Still an amazing ultra rare model kit for any car enthusiast fan. All orders received before 4.00pm Monday to Fridays are shipped the same day.
