HST 01247+0352 is a good candidate for a strong lensed pair.
The red spherical elliptical lensing galaxy (E0) has an apparent color (V-I)=2.1 mag.
The bluer lensed source appears to be point-like with a color (V-I)=0.7 mag.
Two much fainter images can be seen near the detection limit which might make this a Quad system.
The impact radius is 0".08.
The image magnification is about 3.5 magnitudes, making each component about 2.8 mag brighter than the source.
The model gives a reasonably good fit with a normalized chi² close to unity.
