One of four carriages supplied by Brown, Marshalls & Co., Ltd. in 1881 and in regular traffic for many years, this carriage remains unbraked which partially accounts for its longevity; the latter days policy was to not favour the older carraigs which still had wooden brake blocks and these were stored at St. John’ Station where many were lost in the carriage shed fire there on 10th December 1975.  This example was spared as it was still in regular use and stored at the time in the carriage shed at Douglas Station.  In regular use ever since, it was withdrawn in 2019 and extensively rebuilt by off-site contractors, returning in 2022 and in the process of being completed as at March 2023.  One of two to be similarly treated in recent times, the other being F.10 which is due to return to the railway in 2025 for completion.
