Back in March of this year Ted Green (Thor) posted a 10 step installation guide with photos on the old forum (You can click on the "Search Old Board" that appears in the menu on the left side of the screen if you came to this forum via
www.lugerforum.com) and search for "Luger Mainspring Installation" on 3/21/02. Unfortunately the photos are no longer attached to the postings. Perhaps Thor could re-post them on this forum. In the meantime, later on this evening I will extract the text from the old forum and post them here in case you have difficulty accessing the old forum.
P.S. It's Ron. Although I am old, I'm not old enough to be Mr. Wood. (At least I don't think I am)
