  We test possible lensing scenarios of the JVAS system B2114+022, in which two
galaxies at different redshifts (``G1'' at $z_1 = 0.3157$ and ``G2'' at $z_2 =
0.5883$) are found within 2 arcseconds of quadruple radio sources. For our
investigation, we use possible lensing constraints derived from a wealth of
data on the radio sources obtained with VLA, MERLIN, VLBA and EVN as well as
HST imaging data on the two galaxies, which are presented in Augusto et al. In
the present study, we focus on reproducing the widest separated,
observationally similar radio components A and D as lensed images. We first
treat G2 (which is the more distant one from the geometric centre) as a shear
term, and then consider two plane lensing explicitly including G2's potential
at the $z_2$ plane as the first case of two plane lens modelling. Our modelling
results not only support the hypothesis that the system includes
gravitationally lensed images of a higher redshift extragalactic object, but
they also show that the explicit inclusion of G2's potential at the second lens
plane is necessary in order to fit the data with astrophysically plausible
galaxy parameters. Finally, we illustrate a natural consequence of a two-plane
lens system, namely the prediction of distortion as well as shift and
stretching of G2's isophotes by G1's potential, which can in principle be
measured by subtracting out G1's light distribution in a high S/N and good
angular resolution image, especially a multi-colour one.
