Brand: Parker 
Caliber: 12 Gauge
The Trojan was first produced in 1912 and was Parker's attempt to get into the less expensive market at a sales price of $25.50. To keep the costs down, in an effort to appeal to the "average" man, no customer options were offered on the Trojan. This kept production costs down and made the factory processes easier, remember production line processes were not mature at that time. 
Engraving was nonexistent and the checkering patterns were done in a course 12 lines to the inch.
