Charles those flaps have been attach to the trailing edge for a long time. This is a very old plane. It has around 1500+ flights on it.
Thanks for the good vives 
Eddy,
I was looking your photos over.
I wish I could see this model just framed, before covering.
Do you have photos of the model framed?
1500 flights!!

I haven't done that in my lifetime. I should say with CL.

The model really is a good looker!
