Triumph TR3 Hardtop
The steel hard-top Standard-Triumph offered on the TR3 from its first show in 1955: bolted on at eight points, praised for its rigidity, doubted as a coupé, sold in America as the Grand Touring model, and worn by the works rally cars.

When the TR3 was shown in October 1955 it could already be had as a hard-top with sliding side windows, at a price Motor Sport printed beside the open car's. The top was steel, made by the factory, and bolted to the body; the TR Register records that TR3s were also sold new in this closed form. Many of the magazines tested the closed car: The Autocar's SKV 656, Motor Sport's car of 1957 and Karl Ludvigsen's first American TR3 were all hard-tops, and so, by Wikipedia's account, was The Motor's car of 1956. Ludvigsen was clear about what it was not:
It is not possible to recommend the optional hardtop as a substitute for a coupe.
The hard-top in detail
The top was fixed at eight points, The Autocar found, three along the top of the windscreen (windshield) and five round the back of the cockpit, and a spanner (wrench) was needed to take it off. Motor Trend reckoned one person could remove or refit it in about 20 minutes. Inside it was lined, with a large rear window that the testers found easy to see through, and with it came sidescreens with sliding windows.
Eight individual bolts hold down the hardtop, which takes it out of the quick-detachable league, but in return eliminates all rattles and greatly stiffens the car as a whole.
Ludvigsen found that it kept the weather out little better than the hood (soft top): the closed car had the same draughts front and rear as the open one, and in 1957 he wrote that it improved the heating very little; The Autocar, on the other hand, thought its hard-top car as pleasant closed up in winter as it was open. In America the hard-top came in the body colours, and the factory club told TR2 owners in 1959 that the TR3's top would fit their cars if the body was numbered after EB5591. The TR Register also lists a glass-fibre hard-top among the options, without saying whether the factory made it. When the TR4 came in 1961, its own hard-top had a roof panel that lifted out.source 5source 7source 3source 4source 8source 9source 10source 2source 11

Prices and the Grand Touring model
In Britain the hard-top car cost about £64 more than the open car at the 1955 show, and £50 more at the shows of 1959 and 1960; the launch prices are in the TR3's specification. In America it cost between $151 and $165 more than the soft-top car at the ports from 1956 to 1960, and a buyer who wanted both could add a soft-top kit for about $100. Bought for collection in England, a hard-top cost $2,016 with Vynide seats or $2,049 with leather in 1956, and the "GT model" $2,095 in 1960.
Standard-Triumph's American company gave the closed car a name of its own, Grand Touring, from the New York show of 1958 to its advertisements of 1960. In March 1958 it sold the top on comfort over distance:
The grandest thing about this new 1958 detachable Hard Top model is its remarkable, long-distance touring performance.
In competition
The works rally cars, whose record is on the racing page, ran with the hard-top, and the TR Register explains why:
The TR3/3A had a factory steel hardtop - which is what they competed in rallies in as part of what was known as the 'GT Kit' - open cars not being allowed to race under the rally regulations.
How many cars the kit was homologated with is a story told by one source. According to Chris Harvey, as cited by Wikipedia, Ken Richardson had hard-tops bolted to 100 TR3s so that the car could run as a grand touring car after the rules for rallying were tightened in 1955–56; Wikipedia, citing Bill Piggott's Original Triumph TR2/3/3A, gives the GT kit's part number as 554313 and the hard-top kit's as 900711. No source read confirms either.
Nancy Mitchell's works car for the 1957 Mille Miglia was one of the hard-top Alpine Rally cars, Motor Sport reported, and at Sebring the TR3s raced in the GT classes.source 2source 6source 22source 23source 24
