David old buddy, I like them just the way they are. Stately looking. In the eye of the beholder. By the way Dave what projectiles are these I embarassingly ask you. Your collection is one of the best assemblage of WWI German shells i've seen to date.....Always..Dano

The color of the 9 cm Schrapnell 91 was blue. I think it was the same type of blue as they used for the 7,7 cm and other shrapnel shells. After seeing examples of originally painted shells I found out, that the Revell color "Blau, matt, Nr. 56" mostly matches the original color.
