Picture taken about 1911
This photograph is taken from "Powder and Propellants" by Rodney Carlisle.  In the original caption, the author identifies the largest round as being a 16" (40.6 cm) projectile.  However, as 16" (40.6 cm) projectiles of that era were some 56.5 inches (143.5 cm) in length, that would imply that the employee pictured here was a giant of about 7 feet (213 cm) in height.  For that reason, I believe the projectile sizes given above to be correct, which would make the employee height closer to 6 feet (183 cm).
