Hello here is the photos and videos of my DTRS and my customers

bonjour et bienvenue !
belle mécanique

Não há perna na culatra, para a fixação motriz na armação.

il n'y a pas de pattes sur la culasse, pour la fixation motrice sur le cadre .

ah oui , j'avais pas fait attention a la culasse !

Seal by orring instead gasket
