Step 1: Draw two diagonal connected lines. It should look like an obtuse angle. At the joining point of the lines add a semi circle. This will be the trigger guard.
Step 2: Now we will sketch out the top frame of the gun as shown in the diagram. Also add a little hook inside the trigger guard to be the trigger.
Step 3: Around the barrel of the musket add three rings.
Step 4: Above the trigger add a breech, lock plate, hammer etc…
Step 5: Erase any unneeded lines, and mistakes.
Step 6: Your musket is now ready to color.
