As proof I offer a cost schedule from the Hunter Arms engraving department dated 9/19/41 and prepared by Albert Kraus that I stumbled upon in my old files today. Mr. Kraus breaks his cost schedule into two categories; OLD Style and NEW style. The Old Style listed skeleton butts as available in Grades 1 thru A-4 (yes, the A-4 Grade) at an engraving cost of .15 cents for the Grade 1 up to $8 for the A-4 Grade (the A-3 was $3). The New style covered the Ideal Grade thru the Deluxe Grade with engraving shop costs for the Ideal at .15 cents and the Deluxe at $8. And so there is no confusion these quotes represented the engraving shop costs only; this was not the price the company charged the customer to include this option.
