The picture reminds mind of how very many years ago I was finishing off my second ever model, an Airfix Beaufighter, when I noticed that one of the fin flashes was the wrong way round on the transfers sheet, so I had to apply it blue part to the front. (I think I soon became a bit more adaptable).:)

I’m afraid the airfix transfers were accurate, you just needed to rotate it 180 degrees to have it the right way up! (I remember this quandry too!!)
