Another grate assist by JEBIV... not surprised at all.
The fireplace I picked up was in pretty good condition, with only slight crazing on the bottom. It doesn’t appear to have been used very much. The prior owner didn’t use sand, but used a grate to elevate the fire off the bottom bowl. I’m not sure if all fireplaces had the grate (Euro version didn’t), but I do plan to use sand in conjunction with the grate for double protection.
Even though it wasn’t used much, it was really difficult to remove the rusted bolts and nuts, especially on the bottom bowl and lower ring. If I were lucky enough to find one BNIB, I’d start with SS hardware and throw the stock hardware in the trash.
