Completely checked. Some very good scenes of the chubby blond boy on left (here in ep 13). Also another boy (unpictured). One scene of men in Lederhosen an hats at a party inside in ep 10. But in total rather few scenes, mainly of the main character (on right, also cycling in ep7).
Very good scene of both sitting in a canoe and also standing (distance) in ep 7. And a good scene of the chubby boy in Lederhosen without suspenders in ep 3. Unfortunatley I haven't found any other scenes of smooth finished leather.
So still rating "just" 7. Main entry
