I think that there were several different scales used, lima O was 1/48, pola-maxi 1/45, riverrosi was/is 1.43.5 ie the correct scale. There have been some odd items that were 1/50 from the japanise that are listed as O and do run on 32mm gauge track. In the 60's I think that most of the european makes worked to 1/45 which looked right size against british stock at 1/43.5, the buffer hieght being the only giveaway as to the size being wrong!
