I back tracked. I think what got me confused was a piece I saw about Tiger 112 having been damaged and the repairs touched up with RAL 8020 and the barrel looking to be a primer grey replacement Herr Byrden, I believe you are the source of this.
I seem to remember reading that the storage bins on the initial Tigers were not flush with the turret. (photo in the piece about 112 show this.) How big a gap was it? Also, how fast would the RAL 8000 paint fade. I have Vallejo's RAL 8000 , used it on a PaK 38 and it looks awful dark. Fade it with a littlle white?
