Steel window parts

hi,
I have a mid 50's australian triple brick home with steel awning windows.

The opening windows open out like a traditional awing window, however they also
slide down about 150mm, which allows air flow over and below the windows.

However a number of the "winders" have broken, which I am fairly certain i can replace with modern chain awning winders, however the window slides in a track, which is plastic and some of these tracks have broken.

Does anyone know where I can buy replacement parts for these windows, especially these tracks?

Thanks
Simon
