So, my CPR is here and its arrival coincided with the arrival of something else.

Thanks to the gentle enabling by
@aerinha,
@Morgan_Bellini and
@MrsGAM I am now a proud owner of a BT Manor.
The dunk had me uncharacteristically nervous, as there is definitely mystery stiffener in the flap. I ran her a lukewarm bath and kept it pretty brief.
She is currently hanging from a door handle, supported by a chair and soome precariously stacked books in an attempt to get a good handle shape going. She is a beast to shape! Pretty structured though, so maybe she can dry the rest of the way without her towels.
Here are some before photos. I can already tell that the penmarks and the dark stain at the bottom are here to stay.
