New HST and NOT observations of the gravitational lens B1600+434(1) suggest that the lensing galaxy is an edge-on spiral galaxy.(3) We have used these observations to constrain the velocity dispersion (sigma(parallel to) > 150 km/s) and oblateness (q(halo) = (c/a)(rho) > 0.5) of dark matter halo around the luminous galaxy and to calculate the time-delay between the two lens images. The time delay is found to be (54+/-3)/h(50) days using a non-singular isothermal ellipsoid (NIE) halo and (70 +/- 4)/h(50) days using a modified Hubble profile (MHP) halo model around the spiral galaxy. As B1600+434 has shown to be strongly variable in the radio (WSRT) and optical, the system is potentially useful in determining a value for the Hubble constant, once the time delay has been measured.
