What are they worth: B400 regulators?

[hotrodA]

Doing the glass install on my 32 Tudor, and the front window regulators that came loose with the car turned out to be...……..

B400 quarter window regulators, per David Rehor, vol 2, pg A-14-40 P/N B-403200 & 201

So, 32 gurus, what are they worth? Definitely unique in design, not reproduced, and in good working order with only light pitting under the paint on the arms.

Thanks!
