Delivered in 1977 as Muncaster Castle,

she was renamed EASTERN SUMMIT in 1981 and shown here prior to a CMB charter where she initially was not renamed but in 1992 she finally became CMB SUMMIT. In 1999 she was sold on to become TOPAZ and then TOPAZ I, before going to the Chinese, to enter the final part of her career as JU BAO MEN. She lasted another eight years before meeting her fate at the Gujarat beeches.

It looks on this photo that she may have been operated by Rickmers for a while, without being renamed. Must have been 1982 or thereabouts.
