Hi Ward,
Photo of spring and hammer sear without cover. I cannot cock the hammer with bits in position as per photo. I compressed the spring by external means to the next position and engaged the trigger sear, I was able to fully cock the piece but when I released the trigger the spring brought down the hammer as it should but it, the spring, disengaged from the hammer sear resulting in the spring protruding from the bottom of the lock just the same as when I first removed lock. I am sure there is too much wear between the mainspring and the hammer sear and this wear is enough to guarantee that they will disengage from each other every time. This is why the lock appeared at first not to fit or to be a replacement as the disengaged spring had pushed the whole lock upwards causing the crushing effect to the brass sheet adjacent to the top of the lock. Without either making new spring or new hammer sear I don't see how I can get lock to work properly, I think for display I will remove mainspring, keeping it safe of course, so that I can engage hammer in first cocking position so that the pan cover will close. If you have any other suggestions that would be great.
Thanks again for your help.
My Regards,
Norman.
