Battered Blenheim - part 2

Work on resurrecting my badly built (not by me!) Airfix Blenheim Mk.IVF is now well under way.

Repair work included 'folding' the main undercart legs - they were already broken so a bit of work with pliers, knife and glue saw them suitably recessed.  The turret guns were a bit precarious and both fell off while I was sorting out other issues.  I replaced the barrels with a piece of bent florist wire.  The transparent parts were in a sorry state - covered in glue and/or badly aligned, so there was no option but to paint over them.  The two surviving prop blades were next to go.  As mentioned previously, the kit had been built as the Mk.IVF version with it's under fuselage pack of four MGs - astonishingly all four barrels have survived!
Being a Mk.IVF rather restricts the marking options - and ruled out the Romanian and Finnish versions which some readers (who clearly know me well...) had predicted.
Fear not - I managed to find a suitably esoteric scheme.  All will be revealed soon.
