This may or may not be error-ish but....
Pg. 256~257, Field Manual: 3145
For determining cost of the item ( QuadVee Conversion Equipment) the cost is listed a "WSCx0.5". Because there is no note for what it means on the Weight & Cost Formula Codes (Pg. 411, TO), I'm not 100% sure what the math is referring to.
Suggestion: either add this definition in the Supplemental Thread and/or at to a future reprinting of FM:3145 or please tell me the reference pg. that "WSC" is listed? Thank You!
