Dave, certainly an interesting photograph of her without the Funnel and her Ports enlarged, wonder if she was used as a RNR or ANother type of Drill ship in later life although no mention in write up. Ron@?
According to Colledge Jumna became a coal hulk in 1893 and numbered C.110, sold in July 1922 to A J Hellyer as a hulk and named Oceanic. The naval interest then ends.
I think possibly there must be something adrift in her history which is not surprising, if you look at the last picture she looks as though she is still flying the White Ensign, although she has no Funnel, still has her boats and Masts, certainly does not look like a Hulk in that picture neither does she look seagoing. She may well have been an accommodation vessel before becoming a Hulk I suspect.
