Recently, my neighbor tore down an old retaining wall and sidewalk in front of his 1900 Colonial Revival. My partner had all the old bricks dumped in our driveway, and now has more than 1000 cleanedof the old concrete. They say A B & T Co Little Rock on them (I have photos). Some of them look like they were in a fire, and some actually had been dipped in parafin wax. By the time they are all clean, we will have close to 1700 of them. We live in the historic district of Hillcrest (originally a town called Pulaski Heights) in Little Rock, Arkansas. I believe that AB&T Co Little Rock was originally Arkansas Brick & Tile Co. Any information would be great! I will also try and download a couple of pictures I have of the brick. THANKS SO MUCH!!!
