Hi Anon and Whitley Project
Thank you for your replies, in regards to where i purchased these relics around 6 years ago, they came from a dealer who was based in Hythe in Kent, i purchased 5 boards a Blenheim from Sarre, airfield relics from Manston, a late War Spitfire from Whychling and a Meteor from the Bromley area, all these relics were within the Kent region so i would imagine the Avro Anson relics originated from this area, all the other boards were labelled bar the Anson as unfortunately this was lost by the previous owner all remaining was the safety pin and a tiny piece of the card, i feel these would of come from the same collection at some point, even possibly someone who may of been a former Archaeologist.
The boards were displayed on the same type of hardboard that looked very 1970″s.

Its interesting that you have narrowed it down to the N serial prefix if you dont mind me asking how was this achieved? also another good suggestion that you have mentioned as a possible way of narrowing down the search via the mod plate.

I can now confidently put an i.d to the wind deflector i tried but up to now have found no images to show this in situ.

Also with displaying the images there is always a chance that someone may recognise them and help to find its identity.
