Chesterfield style sofa in vintage brown leather

A Chesterfield sofa made of vintage leather. Three seats with cushions and two small leather cushions. The leather is in good condition, in its juice at the cushions only, with a normal wear of an old leather (see photos). The back restless and armrests are padded - metal nails. The only defect (see photo) could be a missing seam at the armrest, but can't be seen (you have to spread the seam to see it).
