17 Pump pegs and bottle cage mounts
Pump pegs - very early Tommasinis sometimes had pump peg on the underside of the top tube near the seat lug (see the blue ’Stencil Thomas’ bike above).
In the mid-1980s we see head tube pump pegs appear. These became standard on all US models in 1986, though from one article it seems they started to be used in the US during 1985. Any 1980s or early 1990s US Prestige, Super Prestige, or Racing Tommasini that lacks the HT pump peg is pre-1985 and likely pre-86.
Head tube pump pegs also appear non-US bikes from 1985/86 onwards, but are often absent. It seems they were never standard in any other market. At some point in the 1990s pump pegs stopped being a thing, but I haven’t tracked when they went extinct.
Bottle mounts - All but one early Tommasini has at least one set of brazed-on bottle mounts. In a couple of these early bikes the mounts are “proud” and much less subtle than later versions. It appears Tommasini was doing bottom cage braze-ons at least from the very early 1970s.
Bikes with two sets of mounts start showing up in the early 1980s, possibly as a special order element. Like HT pump pegs, Bill Lewis asked Tommasini to make them standard on US bikes starting in late 1985 or 1986. A single set of bottle bosses continued to be common on non-US bikes throughout the 1980s, even on Super Prestige bikes.
