Trams of Australia
This is Adelaide's drop centre tram design. These trams becamse the mainstay of the Adelaide fleet. Seventeen of these cars had their seating capacity reduced to 56 seats when a driver's door was fitted to the saloon bulkhead.
These are similar to the F's, except that they had all steel underframes. Twenty two of them had their seating capacity reduced later in the same way as the type F trams.
Thanks to  Tim Blythman and  John Radcliffe for this information.
 Thanks to Kym Smith for updated information about type F at AETM.
