  We present a photometric study of the globular cluster systems of the Fornax
cluster galaxies NGC 1374, NGC 1379, and NGC 1387. The data consists of images
from the wide-field MOSAIC Imager of the CTIO 4-m telescope, obtained with
Washington C and Kron-Cousins R filters. The images cover a field of 36 x 36
arcmin, corresponding to 200 x 200 kpc at the Fornax distance. Two of the
galaxies, NGC 1374 and NGC 1379, are low-luminosity ellipticals while NGC 1387
is a low-luminosity lenticular. Their cluster systems are still embedded in the
cluster system of NGC 1399. Therefore the use of a large field is crucial and
some differences to previous work can be explained by this. The colour
distributions of all globular cluster systems are bimodal. NGC 1387 presents a
particularly distinct separation between red and blue clusters and an
overproportionally large population of red clusters. The radial distribution is
different for blue and red clusters, red clusters being more concentrated
towards the respective galaxies. The different colour and radial distributions
point to the existence of two globular cluster subpopulations in these
galaxies. Specific frequencies are in the range S_N= 1.4-2.4, smaller than the
typical values for elliptical galaxies. These galaxies might have suffered
tidal stripping of blue globular clusters by NGC 1399.
