Seller is in Germany. His auction description, roughly translated, reads:
"Locomotive runs in both directions
Light change red / white
Prepared for digital operation 21P decoder
Light traces of glue from attaching the railings. Only used in test operation.
Further accessories, manual and box."
Photos suggest not a great deal wrong with it. It might actually run perfectly. May only need a DCC blanking plug, so.
13 Euros to post form Germany to Britain.
Might be alright to convert to 21mm gauge.
