Looking good Chris
Apologies for my long absence, being busy at work and having my PC expire have kept me away from FS for a while.
I had a chat to my Dad and we looked through truckloads of reference including various pics of Tigers under construction and under repair... and the final definitive answer...
Some aircraft have two nose ribs between each main rib, while others have one. We also found written reference to say that there were three nose ribs between each main rib
We couldn't work out which came first, or what the criteria was for having one or other, but suffice to say any of these could be termed 'correct'.
As far as the main ribs go, going by the photographic reference we looked at there appear to be 10 full size main ribs but with a smaller one close to the tip - if that makes sense?
I have come up with a couple more pics that may help. Unfortunately I never took a decent pic of the fin/rudder logo at the time so this is the best I can offer at present.

A bit distant I'm afraid, but I have asked a few friends to have a look for any they may have taken.
Here are a couple more that may be useful as well.



I will be heading over to the Tiger's home airfield on the 21st of January to attend an airshow, so if there is any specific detail you need then I can get it for you then.
Keep up the good work.
Steve
