Thank you, D1566 and Planemike.

I had searched the ‘Flight’ archive but could find nothing for the post 1934 period relating to the sale of the Mouse prototype and the eleven part complete airframes.

I’m very grateful for the extract from the Meaden & Fillmore article in Air Britain Archive. If the authors don’t know what happened to the prototype and the part complete airframes, then I suspect that their fate is now lost forever.

So it seems that this is another one to be filed under “dead end” in my obscure aeroplanes file – unless someone else out there has information to suggest otherwise!
