Great condition: a Denayrouze Divers Air Pump made by Charles Petit. The dial of the gauge is signed with 'Charles Petit & René Piel' so this pump probably dates from the era when Petit and Piel (René Piel was Charles Petit's son in law) were cooperating. This period lasted a few years only so this is a rare variation. After Piel took over the company all equipment was signed with his name only. The Denayrouze brand was established by Rouquayrol and Denayrouze in the 1860's and was owed by different people since. Condition see photo's. Price €2900,- plus shipping.
