Help identifying this glazing piece

Please help. Looking for least expensive option that will work well.
Attached is a label from inside the window and profile of the glazing piece. Here are some measurements:
Flat: 3/16
Trough: 1/8
Rounded section (straight across): 3/4
Full diameter: 7/8

Need the following lengths (the following sizes are a few inches longer than the current glazing pieces):
2? x (4)
30? x (4)
3? x (14)
4? x (12)
5? x (2)
Thank you.
