I have started this thread because there were questions asked about a certain type of action in one of my SxS guns.
Soooo, for those not informed and who would like to learn, here are just a few- there are many more however !
Here are four guns , (all black powder cartridge), all hammer doubles, but with distinctly different actions.

The top one is a pretty common bar action lock, with the springs towards the front of the lock, and a round body underneath the barrels.
The the action body for the hinges and barrel etc are exposed.
The second from the top , although a bar action with the springs the same as above , is called a bar in wood, because the action body is enclosed in the stock.
Note the picture below to get a better idea.

The third down is again a bar action lock but the lever is a Jones style under lever opening , the opening lever is not a top latch like the two above, but is under the trigger guard.
And the one below that is what is termed a BACK ACTION lock, because the action side plate and springs extend behind the hammers.
This also has what is called a Lafeachuax action and is seen on many back action guns in particular.
You can clearly see the iron forend bit in the below photo, and the differences between the two underlevers.



hopefully more members will post in pics of any particular action types they have on their guns!
