This is a NOS pair of backing plates for the starfish brake drums.
They are not perfect, they've got some surface rust from its storage over the last 6 decades - which is normal, because they sprayed the paint onto the bare metal, without using primer.
This pair has never been fitted.
OEM-Nr.: 311 611 639 A and 311 611 440 A (we believe what is written on the stickers, because they can compare to others)
VIN #76 300 till #221 974 - PRE 1500S
