Question for Verona Fathers (Comboni Missionaries)

Can you please help me to get a copy of the Ngakarimojong-English. English-Ngakarimojong dictionaries which Verona/Comboni published some years ago? I badly need it to transcribe field notes I made in Karamoja in the 1950s but can find no copies in US or Britain. Whatever the costs are I will cheerfully cover them.
