Window parts

I wanted to know if you had any parts for my window. Its from the 1950s. Id like to restore rather than replace.The coils are a disaster and i can't open or shut the windows very easily. I think the black plastic balancers are broken also. It takes 2 different types. On one side there are 2 long black plastic pieces and on the other side it looks like there is one long black plastic piece. Are you familiar with these windows in the pictures? They open from the top and bottom. so I think i might need all the sliding mechanisms for the top and bottom windows.
