[DCRM-L] Collation: partially duplicated signing

[Randal Brandt]

I am cataloging a book with partially duplicated signatures and would 
like some advice. The book is an octavo in 4's and the preliminaries are 
signed as follows:

unsigned gathering, B, b-i

The main text is then signed:

B-3X

My question is about the initial unsigned gathering. Would it be 
recorded as '[A]', '[superscript pi][A]', or 'pi'? The second gathering 
has to be signed '[superscript pi]B' because of the duplicated B 
gathering that begins the text. At this point I'm leaning towards 'pi' 
since 'A' is not used in any of the subsequent sequences, resulting in a 
signature statement as follows:

pi^4 [superscript pi]B^4, b-i^4, B-3X^4

Any other suggestions? I've looked at Gaskell p. 331 and Bowers p. 219+, 
but do not see this particular situation.

Thanks!
