Man, am I glad that we got to a separate page. It got boring scrolling back and forth on this great discussion. I lost track more than once on the topic. I have a problem on an artillery that won't close the toggle and has a loading/unloading problem. The toggle closes to within about an eigth of an inch of full closure. At first I thought it was dirt a little notch in the barrels cone that the extractor fits in at closing. Now I am wondering if this is a problem with the mainspring? I am sorry that I am a bit OT but this is something that has been hanging me up for a long time.
