The cockpit area reminds me of an Armstrong Whitworth(?) Ensign
Fairchild Packet, even?
I too have a soft spot for Vanguards, some of my first flights were on 'EP & 'EN. I lived as a boy near the "GM" ndb (BHX) and the BEA Vanguards flew up the 328 radial from Garston to GM, then Lichfield. I can hear those Tynes now!
One of these days I'll scan my photos and post them.
