Ann, If it's the Tamron Adaptall SP Macro Close Focus 70-210 f/3.5 with a 62mm filter ring, grab it. Introduced 1984, it's the only non f/2.8 zoom that may be sharper than the Pentax 70-210/4 PKA. It's an all-metal pro-quality lens. You can see and appreciate the difference in speed when you focus through a split-prism rangefinder patch. It has a unique hood that slides in an out to change length to match the focal length you've selected.
And how about that continuous magnification of 1:2.6X? Tamron Adaptall adapter for this lens come in two kinds. The PK adapter will let you use f/32. The PKA adapter will give you all the benefits of a PKA mount but will limit your minimum aperture to f/22. If its 860 g weight proves too heavy for you (the Pentax is 680 g), you can sell it to users of any bayonet mount.
