I have a photo of one *somewhere* which would need scanning. I will go hunting this evening. Meantime the four are *thought* to be currently as follows
ZE410 @ Yeovilton, Cobham Hall storage facility
ZE411 @ MoAF, Middle Wallop - awaiting public display
ZE412 @ Arborfield
ZE413 @ Hereford (for local static display?)
