I did some research a few years ago when we were planning our club layout (Yendys), mainly searching the internet for photos. In the end one of our members sourced (and assembled & installed) all the catenary using a European brand (can't remember which, but an "accessorry" manufacturer, not a "train brand"). However it quickly became obvious that although there were periods when a particular physical type of mast might have been "in favour" (or even "official"), nearly every mast was unique in some way, either because of physical requirements or because it was older/newer than its neighbors.
For example, go to Rolfeworld (http://www.nswrail.net
), go to Photos (across the top), then order them by date. The second page has a photo of Loftus in 1940, and from then on there are lots of photos of the 1960s, and it's easy to pic the catenary masts and expand the photos. Everything from major meccano constructions, to 3 pieces of I-beam, to telegraph poles.
