There are 3 pieces of chrome trim on a 101 door - excluding the window winder & door handles and the pull handle at the top
Here are 3 fairly good pictures, the light green car is missing the pull tab and the blue door car is missing the oblong 'button' to hold the pocket together. Both pieces are shown on the red car.
The blue door cards are original - all 3 cars shown here are Series II Interim / Transition cars as they still have the stripy 750 cloth & not the speckled Salt-and-Pepper (sal-e-pepe) cloth which the later 101's got. That aside, the chrome trim is the same for all Series II cars. I chose these pictures as they show the trim best of all.
The door pull tab trim & the oblong 'button' can be made with a bit of fiddling, but the long chrome trim with the 2 bends will be somewhat more of a challenge......
