Spaans - Desk set (4) - Spaans - Wood, Leather

This type of furniture was originally inspired by 17th-century Spanish/Flemish Baroque furniture, but it was mass-produced in large numbers from around 1880 well into the 20th century — often in Spain, Belgium, or the Netherlands. Given the finish, the condition of the leather and the wood in your photos, I would say this ensemble probably dates from:

Late 19th century to around 1930 (the classic "Spanish Renaissance revival" period), or
A later, somewhat rougher reproduction from around 1960-1970 — this was very common in those decades as "style furniture" for living rooms and study rooms.
