Looking for Latches, pivot shoes and balances for this window

I'm unsure of who made your window, but I think we can replace all three parts you've named. I just need more data before I can make recommendations.

The best place to start is to remove an intact and undamaged version of each part from the window so that we can see what you have without obstruction. In the case of the balance, I need a clear picture of the top end, bottom end, and the stamp printed on the channel. Lastly, for the pivot shoe, please tell me its width and thickness.

With that data, I'm confident I can find you a good match for each part.
