In the early '80s I gained 1 1/4" in length by low vacuum pumping then gently jelqing afterward. It took 2 years and most of my gains were made in 1 1/2 years. I began by warming my penis with a moist towel and followed that with 5 minutes pumping, then 25 jelqs. Eventually I pumped for 10-15 minutes then jelqing to the eventual count of over 150. Performed the routine 3-4 days then take a day off.
