RN348 – Hannes Paling’s response to Dave regarding the NGG 11’s mechanical lubricator

In response to Dave Richardson’s query (RN347) on the fitting of mechanical lubricator at some stage to the first order of NGG 11’s numbers 51,52 & 53, I have a page which appears to have come from a Beyer Peacock catalogue, showing NG 51 fitted with the lubricator when new, it looks like a works picture. Perhaps they were removed at a later stage, I include a scan of the page, hope this solves the mystery.
