It just might be a Modav 'Sea Vixen'. I had nothing to do with its design and I'm pretty sure that production stopped when the Fairey Huntsman kits came out. Googling it only finds a plan for one sold a while back on E-Bay, and there's no picture. You might be able to trace the buyer via the seller……..
There's not much left to do from the looks of the picture; just the front windscreen (which looks like a vee-shape in two halves) and the cabin roof (ply bent to the curve of the main bulkhead).
I'd suggest mocking these up from card and seeing what shapes you can obtain and what you prefer.
Good luck!

This example is up for sale on ebay, its not quite the same but it does provide the 'as built' information

No problem Dave

But to be charitable maybe that battery is the only one they had and it might have shared between many models.
