Displayed as P4139, a Fairey Swordfish I of 813 Naval Air Squadron, this is really HS618 and has previously been displayed at various times as V6105 and W5984. HS618 was built under license by Blackburn and delivered to 834 Naval Air Squadron in May 1943 where it went on to serve on the Escort Carrier HMS 'Hunter' in the north Atlantic. During bad weather a Seafire broke loose in the hangar deck and struck HS618 and it was written off, although it continued to serve as an instructional airframe.
