 Apart from a spell in the 1980s and 1990s when it was produced and edited on the mainland, the magazine is produced entirely on the island and reaches a membership of approximately 1,000 usually four times a year but the fact that it is entirely prepared by volunteers can mean that the number of issues per annum fluctuates.Members and non-members alike may contribute articles and photographic material for reproduction within the pages of the journal.In 1992 the magazine celebrated its century (one-hundredth issue) with a colour cover, something which had only been seem three times previously, one of those being for the centenary of the railway in 1973.
