Tiny flat spring in the handguard of my GHE that keeps tension on the release level i

[Kevin McCormack]

OK; it's simply a forend release latch spring (not the flat top lever return spring I referenced earlier. A "hand guard" is a leather-covered metal sleeve used on splinter forend guns to protect your fingers when the barrels get hot). So its more or less a specialty item that you are not likely to find readily available unless someone has a sizeable Parker parts inventory. Kensal's idea of having it laser welded is a good one.
