Not really a ”weapon of war” – But still a cool piece of paper I had kicking around… You can click on the photo for a larger view. The text from the back of the paper is below.
General Instructions – Mossberg Model 188D-B
.410 GAUGE BOLT ACTION SHOTGUNS
1. To Assemble Gun

2. TO LOAD
Open action by raising bolt handle and pulling bolt back as far as it will go. Insert 3 shells, one by one, as shown in sketch. Note from sketch that the head of each shell is placed slightly in front of the shell beneath it. Push bolt forward and push handle down to locked position. The gun is now ready to fire.
3. SAFETY
When the thumb safety at rear end of receiver points to red button F in stock it means DANGER, as the trigger can be pulled and the gun FIRED. When safely points to green button S the trigger cannot be pulled, therefore it is on SAFE.
4. TO EJECT FIRED SHELL and LOAD NEW ONE

7. TO REMOVE THE BOLT
Raise the bolt handle and pull the bolt back..as far as it will go, then pull back on the trigger and the bolt will slide out.
8. TO REPLACE BOLT
The gun has a two piece bolt. BE SURE to line up the marks on the bolt an bolt head before inserting the bolt, then insert bolt holding back on the trigge with one hand and pushing forward on the bolt with the other. NEVER force the bolt into the action, for if lined up correctly bolt will slide in easily.
