Beautiful! I'm pretty sure you got the chevrons right too. I've read that the engineers had gold-colored chevrons like they are in your colorized photo. Dumb question but I'm just wondering if there was any confusion with the cavalry who also had gold (or yellow?) chevrons. Was there a difference in the shade of it, with the cavalry chevrons being more bright yellow and the engineers' being darker than the cav, more "gold looking" of a shade? Or did they have truly identical chevrons and the main way you could tell them apart was by the cavalry of course being on horseback and the engineers generally being on foot?
