The narrow dome is an interesting variety in the 162.1 Brookfields. I have found it comes in both a short skirt and tall skirt variety both of which I have in my collection. This piece is the [055] EID and 43 drips which is consistent with the examples I have. Most of these have some light olive swirls, and this one is not an exception. It also has some light carbon swirls in the dome.

The [055] EID is (F-Skirt) BROOKFIELD {narrow dome variant} SDP

Note how the embossing isn't centered vertically on the skirt and it is lower than usual. This is likely due to a mold rework to reduce the amount of glass utilized.
