In ME 1942 F.C. Hambleton had a long series of articles on loco headlamps of the pre-grouping and grouping railway companies.
Before you ask I don't have many of the articles myself, but a trip to your nearest main library will get you access – for me it would be the library of Birmingham, but Nottingham Central Library also used to have a complete set of old ME magazines for reference. Or perhaps your club might be able to help if you are a member of one. Have a look at the online ME index to see which articles would be of interest – but I suspect they would all be in a single bound volume.
