I would wager that your flywheel is a Manfred lightened piece. I have dug around for pictures of the one he did for my LM but can't find anything. I'm sure I have it somewhere in an old box of pictures. Memory may diminish after 35 years but certain things stay fresh when they make such an impression. I vote for keeping it in there. If you decide not to, let me know and I'll make you a nice stand to display it on. More art for the office!
