This is the three-part mould variant of the Brookfield blobtop. No MLOD. It has lots of easily read embossing going in concentric circles on the dome. Nice sparkly blue color with great clarity to the glass. Contrasts nicely with a "cottonball" of unhealthy looking yuck you can see in photo just below the wire ridge. A clean flat base chip and a couple pecks / flakes elsewhere are all to mention for damage. Fairly rare blob, and a good looking one to boot ! Can't go wrong at:
