RBH Note: This price list stresses the point that the number six strength cap should be used with all high explosives. It's interesting that duPont chose to continue to supply the lesser strength caps - but lowered the price of the #5 or #6 to be closer to that of the #4 and #3.There were imports of the lower strength caps at the time that had to be competed against, hence the price reductions. Another interesting point on this price list is the noting on the "Red Cross Explosives" page that these explosives reduce the danger incurred during the operation of thawing. As noted many times in these articles, this problem was not to be solved for about another 16 years or so.
