Hi again,
Regarding the NBC PEC I have...
I believed that it's shoe (2x holes) was only used on the Vulcan, however I have learnt that later Victors used a similar shoe (early ones used a Lighting PEC).
BUT I have just found another aircraft that used a similar shoe, the German F4-Phantom, (these are not my pictures):
Now, my NBC PEC will not fit this seat, as the key dowel is on the wrong side, so I don't think it's for a German F4 Phantom (and it has a UK NATO socket, the German F4-s used a US NATO Socket), but if some of these seats had the PEC on the other side, or the block the other way round (conventional UK style) then my NBC PEC could be from a Phantom...
I'll have to research the UK Phantoms PEC's.
Still to find a conclusive answer... I think PN suggested I contact MB with the part number, may be easier!
Cheers, Scott.
