We have investigated different scenarios for the origin of the binarymillisecond pulsar PSR J1911-5958A in NGC 6752, the most distant pulsardiscovered from the core of a globular cluster to date. The hypothesis that itresults from a truly primordial binary born in the halo calls foraccretion-induced collapse and negligible recoil speed at the moment of neutronstar formation. Scattering or exchange interactions off cluster stars are notconsistent with both the observed orbital period and its offset position. Weshow that a binary system of two black holes with (unequal) masses in the rangeof 3-100 solar masses can live in NGC 6752 until present time and can havepropelled PSR J1911-5958A into an eccentric peripheral orbit during the last ~1Gyr.Comment: Accepted by ApJ Letter. 5 pages, 1 figure, 1 tabl
