I'm sure that would be the case John.

You raise an interesting point about drop-centre designs.  I think that both the L class and F type were influenced by earlier designs.

The Hawthorn Tramways Trust bogie cars had four drop centre doorways like the L and F trams.

I have attached a sketch of what the Ls originally looked like. The Ls were later converted to 3 drop centre doorways and that became the Melbourne standard until sliding doors.

The other earlier bogie cars with 4 drop-centre doorways were the VR cars, dating from 1917.  See https://tdu.to/i/11134

Two of the panels on each side of the VR bogie cars were just posts - because the VR trams had shorter truck centres than the MMTB or Adelaide trams.

All three types used Brill 77E trucks.  Were they the original trucks used on the F type?

I am certain that there was a lot of sharing of ideas in that era.
