Quite right Grahami.Must be at a guess 1940ish catalogue,but unfortunately there is no date on it.Shows the Llechwedd blondin with its unusual tipping arrangement (like some of the Solomon Flory cableways in America)working in 2 photos,so as it had a relatively short life Llechwedd fans could no doubt get an approximate date.Its called `Henderson Arial Cableways In Quarries`,and is 12 pages long,and has pictures from as far away as Mexico:Henderson products have travelled all over,and still do.They now make massive kilns and winches,and moved from Aberdeen to Arbroath recently.It also shows radial cableways (with a moving tail tower to sweep a quarter circle).
Would I have to contact Hendersons to upload it?I have it saved to a disc,just in case.If you wanted to see it how could I easiest get it to you (without of course causing trouble regarding copyright!)
