Löschgruppenfahrzeug the right games

So myself am a firefighter and what can I say, the apple does not fall far from the tree. My kids always play when they can with the fire brigade. Unfortunately, not all vehicles have the same sounds. The fire chief car has only the siren, the DL & the LF have Martins horn and the rescue vehicle has no sound at all. Unfortunately, this is a pity. Here Playmobil could rectify therefore with the other products a star deduction
