Blenheim IVF I`m looking for infos !

Hi at all

I am desperately looking for informations about the Blenheim IVF (fighter)

It was armed with 5 fixed machineguns (1 in the wing, 4 in an underbelly pack).
With the underbelly pack a reflektor gun sight was built in.
Does anybody have an image (foto or drawing) of the cockpit of an Blenheim IVF (with the gunsight visibel) ?

If Yes, would I be verry happy if You could post the image !!!!
