Aims. We have analysed VLBA 92cm archive data of 44 extragalactic sources inorder to identify early targets and potential calibrator sources for the LOFARradio telescope and the RadioAstron space VLBI mission. Some of these sourceswill also be suitable as in-beam calibrators, permitting deep, wide-fieldstudies of other faint sources in the same field of view.  Methods. All publicly available VLBA 92cm data observed between 1 January2003 to December 31 2006 have been analysed via an automatic pipeline,implemented within AIPS. The vast majority of the data are unpublished.  Results. The sample consists of 44 sources, 34 of which have been detected onat least one VLBA baseline. 30 sources have sufficient data to be successfullyimaged. Most of the sources are compact, with a few showing extendedstructures. Of the 30 sources imaged, 13 are detected on the longest VLBAbaselines (approx. 9 Mega wavelengths), while all were detected on baselinesgreater than 2 Mega wavelengths (the maximum baseline of LOFAR including thecurrent international baselines).
