Tamron launched their first 80-210mm consumer zoom (model 03A) in 1979 as one of the initial line-up of Adaptall 2 lenses. It was replaced in 1981 with the model you see here (model 103A) which lasted until 1986, The 103A had the same zoom range and aperture, but improved on the 03A optically and featured high quality metal construction and good ergonomics. It was one of Tamron's most popular and long-lasting models, but in 1986 this lens was replace with the model 46A. The 46A lens had a slightly expanded 70-210mm zoom range and was slightly lighter (580 grams vs. 634) but featured cheaper construction with much more plastic than the 103A and lost some of the practical features of the 103A like depth-of-field scales. If you are looking for an inexpensive lens with this sort of zoom range, the 103A is the best of the 3.
