Pierrotin's present establishment consisted of two vehicles.

One, which served in winter, and the only one he reported to the tax-gatherer, was the coucou which he inherited from his father.

The rounded flanks of this vehicle allowed him to put six travellers on two seats, of metallic hardness in spite of the yellow Utrecht velvet with which they were covered.

These seats were separated by a wooden bar inserted in the sides of the carriage at the height of the travellers' shoulders, which could be placed or removed at will.

This bar, specially covered with velvet (Pierrotin called it "a back"), was the despair of the passengers, from the great difficulty they found in placing and removing it.
