Your quite right about my list not being complete, but I don't claim to be a AVRO historian
There's a picture here of the original A.V.Roe hangers
AVIATION NORTH-WEST - WOODFORD AERODROME
And there's a A.V.Roe museum of sorts
Aeroflight Avro Heritage Centre
Last but not least the WiKi for AVRO
Avro - Wikipedia, the free encyclopedia
I'll try and find out what the plans are for the clubhouse and museum, I should imagine plans have been made but kept under wraps for the time being.
If I find anything out I'll post here.
