Now that I have the majority of those details worked out, could some one help me with the cylinder stop. I cannot tell how the trigger interacts with the cylinder stop to lock the cyl. when the hammer moves to battery. This model does not have the spring to assist the stop upwards when the lock work is manipulated that is drilled towards the front of the trigger bow. It seems as if the trigger has a protrusion which interacts with a small spring loaded detent to move the stop downwards actuating the detent and then may return the stop upwards when it comes to rest. I cannot find a good representation of the protrusion on the trigger to study. I only find the most information or reference to the later hand ejector models which have more parts inside the frame. Thanks for any help that is out there.
