Thanks Tony, yes it does say 1/48 they do look quite large! Although it does say by the Puma 1/32, they won't fit my 1/72nd Fouga.
GttC, we used to play with 3-KE but not as a training aid so much,like I said we put the perspex over the airbrakes, I seem to remember we were going to re-skin the belly but never got around to it.
The Fougas were definately painted aluminium, not bare metal, not shiney.
