HST 01248+0351 is a good candidate for a strong lensed pair in the same WFPC2 field as HST 01247+0352.
The edge-on disk lensing galaxy has color (V-I)=1.2 mag.
The bluer lensed source appears to be point-like with a color (V-I)=0.7 mag.
The impact radius is 0".05.
The image magnification is about 3.1 magnitudes, making each component about 2.4 mag brighter than the source.
The model gives a good fit with a normalized chi² close to unity.
Spectroscopy is required to confirm this candidate as a gravitational lens. It is included in this sample as the best candidate for lensing by a disk.
