Further digging into the SLQ and BTMS collections has revealed that there
may have been four of these cars, as I have found photos of Nos 23 and 24.
The number on 23 is very clear, but on what I believe to be 24, it is
indistinct. However, if you look at the zoomed snip, there is a blurry 4
and a ghostly 2.
The car also has the same roof shape and seating arrangements as the other
three, so I'm calling it 24 on that evidence.
I have also added a photo of No 26 single deck horse tram to show what they
were like before conversion to electric cars.
Robert Thompson may know more about these cars and may correct me if I'm
wrong.

Cheers,
Mick in Brisbane, feeling excited.
