I remember XH375 being delivered to Southend for conversion to a Saunders ST-27 along with XM295 which was converted by Aviation Traders to become the prototype ST-27 CF-XOK.

I do remember that XH375 appeared to be a very bright red, almost dayglo. It was definitely a lot brighter than any Queens Flight Wessex that I saw over the years.

 At the time I understood that XH375 was also going to undergo conversion to an ST-27 at Southend but for some reason that didn’t happen and having had the registration CF-YAP applied at Southend it seems to have found it’s way to Canada before conversion.
