The HFT tag went out of use after the heavier K-22 Outdoorsman was introduced because it no longer made any sense. At that point the I-frame .22 became the .22/32 Target in catalogs and marketing literature; that's how it was called through the 1930s and after the war until model numbers took precedence and it became commonly known as the Model 35. (One inconsistency: Internal printing on box lids in the late 1930s still used "Heavy Frame Target" in boilerplate language that had fossilized years earlier.)

Kit Guns never had barrels longer than four inches, though you often see ill-informed sellers on auction sites using the phrase "Kit Gun" for any .22/32 of any barrel length. After the 1953 redesign, a two-inch variety was introduced, but I think that's the only barrel length variant in KG history.
