Labeled Diagram of a Lock by L&R.

[Brazos John]

Here is a diagram with labeled parts from L&R Locks.
I still don't know the names of all of the parts, but this should help.
Other locks may be different.
YMMV.

Diagram of Parts – Flintlock​

Disassembly/Assembly Instructions with the Durs Egg Flintlock as “Example”.
Tools: 1/4” flat screwdriver / 6” or 8” common pliars / small hammer & center
A vice is handy, but optional

SEQUENCE OF LOCK DISASSEMBLY

1. Remove main spring: a. Hammer must be all the way down. b. Compress any spring only the amount necessary. Overstress will collapse or break it. A pair of pliers is best.
2. Remove stirrup: Take note that it hangs in the “S” position with small end in the tumbler. Any other position can cause damage! (“Z” position for left hand models only.)
3. Remove sear spring.
4. Remove sear screw and sear. (When reinstalling, tighten screw only until contact is made between bridle and sear. Then back up 1/4 turn, so sear will operate freely.)
5. Remove top bridle screw and bridle.
6. To remove the tumbler from the plate:
   1. Take out hammer screw.
   2. Using the jaws of a vise, tum the tumbler side of the plate down, with the vise jaws only far enough apart to allow the tumbler to fit freely. Now, using a punch that will just fit the square hammer hole, tap the tumbler out of the hammer. Caution: Keep track of the fly during this operation!
7. Remove fly from tumbler. (Take note of the fly’s position regarding its beveled edge. It must be reinstalled in the same way.)
8. Remove frizzen spring screw and spring.
9. Remove frizzen pivot screw and frizzen.

LOCK REASSEMBLY

1. Install frizzen and pivot screw.
2. Install frizzen spring and screw.
3. Install fly in tumbler. (Remember the position of the beveled edge.)
4. Install tumbler in plate.
5. Install bridle and top screw.
6. Install sear and sear spring. (Remember about screw tension.)
7. Install stirrup so that it “hangs” properly.
8. Install main spring. (Be sure tumbler is in relaxed position, as if hammer were all the way down.)
9. With pliers or properly adjusted vise grips, tum the hammer pole to the “half cock” position. Press the hammer onto the tumbler. Install the hammer screw. If the hammer is properly tight on the tumbler, it should not be necessary to do more than “finger tighten” the hammer screw.

Just curious about that last sentence.

 

[Rudyard]

He means the 'Tumbler pin' that holds the' Cock' needn't be over tightened .
translated (. Expecting brick bats for using the gun trade terms). ' bolts ' for lock & tang are called ' side nails' & ' tang nails' there are no internal' screws' they are 'Pins' respectively . Rudyard the pernicaty but Dave Person uses those terms. The only' hammer' on a flint lock is the bit that showers sparks & I call it a 'Steel '.Wedges don't' wedge' There 'Keys ' but they don't ' turn' and go through' Loops '.By now you probably think Ime the loopy one tilting at Windmills .
Don kee Rudyard not de la mancha . But I've been to Cervantes house back in Franco's time. I went to a bull flight he was there surrounded in sea of green & back' Guardia Civil I' bought a bull horn & later made a big powder horn , Kids bought or scrounged them as they played 'Bullfighters ' this was 25 years after the Civil war but plenty of bullet holes& repressed Rural people . Now my Sister lives in Spain a different Planet from my days
