The British High Speed Train HST 125 is a Class 43 and all loco numbers therefore begin with 43...
The prototype in the first post is 43087 so if you had a Hornby example in your collection that was a 47087 it would be a rarity indeed and very collectable!
Hornby made a Scalextric Batmobile about 15 years ago based on the original one in the first film. One of the production team at Hornby walked in Simon Kohler's office with a production sample and asked Simon what he thought of the model. Simon said "double the size of the Batman logo and you can start production".
The production manager was slightly alarmed as 100 had already been produced with the small logo. Simon said don't worry and package them for sale anyway as nobody will notice.
Unfortunately collectors did notice!
This Batmobile with the small logo is a prize possession for any collector and they now fetch ££££ in mint condition!
