That's a nice model you got coming along there. I know you have done research on this plane but if that's a MkV are you sure it had a four bladed prop? I am not sure about those exhaust manifolds either, I thought the MkV had three exhausts either side?

The black and white markings you are talking about were not Battle of Britain markings but D-Day markings. This was to avoid the confusion that ou were talking baout but it was for D-day onwards.

During the Battle of France British planes where painted half duck-egg white, half black on the undersides for identification purposes but this was phased out (I cannot remember why) during the Battle of Britain.

There were no MkVs during the Battle of Britain either. Some MkIIs but only a few. Most of the work was done by the Hurricane Mk1a and the Spit Mk1a...

Oh! Those rivets on the engine cowling were more like screw so that they could take the cowlings off to get at the engine for maintenance BTW.

What are those black lines on the wings all about, I haven't seen them before?

Sorry to bore you will details…
