Cast Iron Riser
Cast iron riser bases measure 9" x 9" x 6" high. Quite heavy!
If I were to guess, I would say these were bases from a balustrade.
Colloquially known as the Pacomia Boyz, Chuy and Chato work at the scrap yard by intercepting trucks headed to sell scrap. The buy items of utility, beauty and value before they are ground into scrap. I have been buying bicycles and another items of interest from them for a decade.
At this time, in-person only.
