Peter: The 'blips' are above the shifter braze-on's and one near the BB, both centered on the bottom of the DT. They have a slight tear-drop shape and have a 'tube' type hole in them, each facing the opposite direction, as if they were a tube and then were form filled around it. I have many bikes with the shifter 'stop', so I know what they are and look like. BT

Bruce Thomson says "I received my new-er vintage JT Touring frame today ...My question is what are the two little blips brazed under the down tube?? They are shaped as though they were made to run a lighting cable through the DT.? ? I tried to clean them out and was surprised to find they did not go all the way through the DT and present an opening into the void to run the supposed cable.? Were these left 'closed' and just up to the shop or owner to drill open and use??? BT"
Depending on their placement, they may be stops for the clamps for downtube shifters, downtube cable stops, water bottle cage, etc. They would keep the clamps from sliding down the down tube.
