for the Use of Uncle Sam's Boys "Over There' 



Barrels being finished on the 

 outside. Bob is here feeding 

 a barrel into a machine which 

 trims it to size and finishes 

 the outside so that it is 

 exactly concentric to the bore 



The cavities in the breech end 

 of the barrel vary in size. 

 The barrel is held in a fixture 

 while Pete (below) uses the 

 different drills on it. The 

 piping delivers lubricating oil 



Adjusting the telescope 

 sights on rifles. The rifle 

 is first sighted on a target, 

 then the telescope is at- 

 tached to the barrel and 

 trained on the same target 



Gathering and assembling the 

 various parts is bench work. 

 John, shown on the left, takes 

 great pride in his work for it 

 calls for almost as much skill as 

 does the assembling of a watch
