Hi Trevor.
Looks (to me) like plate steel welded together at top right. We're talking serious armour plating here? And it looks like (at top left) there is 'nothing' forward of the cockpit, certainly no engine. First thought was the Hs-129 but the internet said "no". I'm thinking of the attack version of the Fw-189?
