The 1928 catalogue was issued two years after the firms Alfred Ransmayer and Albert Rodrian were formally united under one rooftop. It contains the full RaRo product line of the time, which are regular type, special type, but also keys and keytops.

Now we have the catalogue - it's fantastic, because it will allow us to identify the exact specifications of a type, starting from typewriter mounted with RaRo type near you (I am sure also readers outside Europe will have many of those in their collection). You might need a magnifying glass, but if the type is from RaRo, you will find a letter / two letters, plus a number, e.g. "AR 1". This, in combination with the catalogue, is all you need.
As has been mentioned before, even after the fusion of the two companies, the former Ransmayer (Ra) and Rodrian (Ro) production lines were kept up, down to the continuous use of two logos. Type from the former Ransmayer production would bear the "R" mark, whereas Rodrian was "AR". Confusing, isn't it? This means that for correctly identifying the RaRo type used, you need to read not only the number but also the R or AR mark.
how to read the RaRo types: LEFT: Ro(drian) 1, RIGHT: Ra(nsmayer) 58. The reason why two brands are used within the same company is that Ransmayer and Rodrian were separate companies in the beginning.
|"AR 17" = "17 Ro" in the catalogue, p. 23. Available for category 1 typewriters, so: Alexander, Allen, Amata, A.M.C., Atlantia, Commercial, Continental ETC. In fact, this type is from later typewriter, a Patria from the late 1930s.|
|"58 Ra" (I start to read it correctly now, letters first) = "58 Ra" in the catologue, p. 26. Three letters on one typeslug, and this rightly is from a 1920s ROFA typewriter.|
|"AR 7°" = "7 Ro" on a portable typewriter. Catalogue p. 24. Found on a Gossen Tippa.|
|"1° AR" = "1 Ro" on a portable typewriter. It is a Triumph portable (rrrhh, forgot to take down the serial number, need to go back to Alfred's).|
|"R 58" = "58 Ra" in the catalogue, p. 26. Found on a Senta portable, model built from 1913.|
|"AR 367" = "367 Ro". Not found in the 1928 catalogue, so the font probably stems from later. This was found on a rare typewriter, a Matouš portable, # 47180.|
