Nice clean finish on this one...looks like it's ready for the "monument" pedestal (which is where I believe this particular variant actually ended up instead of seeing combat). You did a good job with the pre-war 3-tone scheme as well, definitely sets this one apart IMHO.
Only minor detail suggestion would be on the cleaning rods, the cover for the sponge end was usually a canvas or leather draw-string type cover and the wooden connecting ends had metal screw-thread fastenings. Nothing huge, but something to consider on future builds to add a little more detail if you wish.
