^V^OU may be willing 

 to pay more for the 

 same comfort, style and 

 optical correctness that 

 Shur-ons give, but why 

 should you, when Shur- 

 onscombineall these qual- 

 ities at reasonable cost? 



The genuine, made only by 

 Kirstein, bear the name Shur- 

 on (or Shelltex, if shell-

Passed by rigid 

 government tests, 

 the Parker Process is 

 now being used on 

 army rifles, bayonets, machine gun parts, hand 

 grenades, bolo knives, trench knives, bicycles, 

 motorcycles, mine cases, buoys, aeroplane 

 parts, food containers, bridle bits, stirrups, 

 truck parts and other equipment of war. 



Government Endorsement Bears Out 

 the Experience of American Industry 



The endorsement of the Parker Process 

 for use on war equipment by the U. S. and 

 British governments must prove to the most 

 skeptical that the Parker Process does pre- 

 vent rust. 



This official action bears out the experi- 

 ence of the leading American manufactur- 

 ing concerns who have been protecting their 

 products from rust by the Parker Process 

 for several years. 



A Book on Rust Proofing 

 for Industrial Executives 



No matter what you manufacture— if you use 

 steel or iron you will find it interesting to read the 

 recently published Parker Process Book. This ex- 

 plains how the Parker Process is rapidly reducing 

 the great toll rust takes annually from our steel 

 supply— how it is now being used on metal articles 

 from automobiles to fountain pens— from building 

 hardware to typewriters— and how easily you can 

 apply it to your own product in your own plant 

 without interfering in any way with your present 

 manufacturing plans. To be sure of a copy from 

 the first edition dictate a note at once.
