DH106 I didn’t intend to imply the Avro Manchester was related to the Vickers Wellington

25 deg south I was aware of the relationship of the York to the Lancaster but hadn’t got time to work out a way of illustrating that via the computer keyboard :confused:

My original idea of ‘family’ was concurrent or follow-on designs from the same design office thus the Tudor would be an addition to the Manchester family.

One could argue a family line from the Sopwith Tabloid to the Hawker (sorry BAe) Hawk but I was thinking of aircraft with structural commonalities.
