[PW] Meaning of peca

[Jack Bowman]

Folks,

Context: a document on Nicaraguan exports to the US in the 1930s. Source
text is a report by the US legation in Managua at the time. Author of
the report says that about a tenth of Nicaragua's exports to the US in
1934 consisted of "balsam, 'peca and hides".  Note the inverted comma
before peca, indicating that the word is a contraction.

Can anyone even guess what 'peca might be?

Thanks,
JB
