Farmall M radiator shutters

[farmaholic]

Hey all you tractor restorers, what are the rad shutters for a Farmall M worth?

Not seized, opens and closes. There is some rust pitting on some of the louvers. Just the short flat strap iron linkage connected to it is included.

Are they as scarce as hen's teeth?

I have no idea what they would be worth but are likely very scarce.
I think it was one of the first things that were thrown off.
W-6 probably the same?
