Very interesting! Good spot. It's still there all these weeks later which is a bit weird.Finally figured out what type of aircraft this is!
Avro 748 or possibly a derivative like HS 748
Tried to figure it out a while back but didn't have any success; came across a photo of one today while surfing the web and recognized windshield configuration as being same as shown in this photo. Probably not of much interest to most but thought I'd share anyways.
Cheers
Here's a slightly better looking model!
