Window guides

A landlord from Springfield, MO says:
November 8, 2022
Markings on longer one - 2730 HB then the letters B.S.I

smaller one - 1530 EG then the letters B.S.I

I would need both the left and right guides for each window.
I don't know if the part that the guide attaches to is there/or intact.

Thank you!
