Power Steering Belt-2500/2800/2800cs (69-71) - this is the original 9.5x1125 size that came with the car (possibly important for concour events). Made in Germany.
Note- this one is a "smooth" belt. I also have the "toothed" vesion listed separately. Smooth version are a bit easier to install and were stock back in the 60's and 70's.
