Please help identify these two window balances

A quick learner from Colorado Springs, CO says:
They are both 1/2" tracks, 27" long. It is the bottom fitting that I am not sure of. Thank you.

Thanks for posting. It looks like you have two different balances here. Are these in the same window, or in two different windows? If they were in the same window, which was installed first? One needs to be custom made, while the other does not.
