1. Sendra was making lowers into 1995, so there were absolutely post-ban lowers.

2. Sendra never made complete rifles.  The Sendra company sold lowers only, while a related company (Nesard) sold complete parts kits.  Both companies were owned by Jerry Drasen (Sendra and Nesard are re-arranged spellings of Drasen), but since he was a felon, Sendra was technically in a family-member's name.  He got in trouble again due for tax evasion (evading the Excise Tax on complete guns) eventually.

3. While Sendra marked all of the lowers in their possession after the ban with a circle on the mag well, there were still plenty of them sitting in distributers' warehouses and in gunstore safes that weren't assembled into AWs, and are therefore post-ban, regardless of markings.  A circle-marked lower is a guarenteed post-ban, but a non-circle-marked lower may or may not be pre-ban.

4. Most non-circle-marked Sendra lowers were probably assembled into AWs before the ban, but unless the possessor can PROVE this, he's SOL unless he was the original owner since before the AW Ban.  See the Legal forum for more information on this point; we've rehashed this 10 dozen times too many already.

5. In 12 months, the AW Ban will be gone, and Sendra lowers will be just old, used AR lowers of no particular value.
