[DCRM-L] Symbol used in preliminary signatures

[Barbara Tysinger]

Good afternoon!

The latest in my series of signature queries...

I have a book in octavo, the preliminaries are in a single gathering, 
completely unsigned, followed by an engraved frontispiece singleton 
(also unsigned), and then the main text block, with the title page being A1.

My question, should the frontispiece singleton be recorded in the 
signature statement as: " pi⁸ chi1 A-O⁸ "  or as " pi⁸ 2pi1 A-O⁸ "? Or 
as something else?

The book in question is:

    /Tratado de las operaciones que deben practicarse en la dentadura, y
    método para conservaria en buen estado/ ... by Félix Pérez Arroyo.
    Madrid: Franganillo, 1799.
