DEPTH CHARGES MARK 6 and MARK 7 |

CHAPTER V - INSPECTION AND TESTING GENERAL INSTRUCTIONS |
TESTING PISTOLS |
5. Depth charge pistols should be tested only as necessary to insure their satisfactory operation because continued working of these mechanisms will distort the bellows and cause unnecessary wear on the plunger releasing mechanisms. A pistol to be used only for instruction and drill should be provided where necessary. |
