I am looking for two parts for my 1902/1909 Long Lee Enfield MkI* CLLE

1) Rear sight Elevation Slide, and
2) Rear Handguard

Regarding the elevation slide - the ladder is intact, but the rear sight elevation slide is missing. So I am seeking a rear sight elevation slide as is my most pressing need.

Regarding the rear handguard - the one have has been sanded down to the rivets and cracked. Ive repaired the crack, but the handguard is noticeably diminished. I can live with it, but Id prefer to find one in better condition.
