Probably more a poorly balanced main wheel tire, than nose wheel shimmy.
Had it on two following legs on a Qantas Jumbo (out of FRA, out of SIN). You could see the galleys/toilets above the wheel wells moving in resonance... And it clearly matched the landing gear retraction cycle, which includes braking the wheels at a certain pont, when all the vibration suddenly stopped. Slight vibration could be felt during take-off and landing run at higher speed, but it clearly went extreme just with the wheels off the ground.
Also felt it (to a much lower extent) in the nose of a KLM 747 with a more gradual spindown of the wheels and end of the vibration (also including a fading of the vibartion frequency) after retraction.
