Question about -Work Compr. 7,2V - 64634

Basically everything that can be seen in the picture, i.e.: compressor, airbrush gun and the hose.
You need a 7.2V NiMh battery with a Tamiya plug and a charger for the battery.
If you want to work stationary, I would recommend this set:
Revell Airbrush Basic Set with Compressor
