I used to see a similar steamroller digging up my road in the 1936 - the only item not shown is
the three diggers on the end of the roller. It stopped one morning right outside our house, and us lads gathered round the lamp post outside. As it was working up hill, a workman let down the
diggers by a screw type wheel. Crunch, they dug out the tared road, then a man with shovel
lifted it all up, into a waiting lorry. That was digging a trench for the main drainage - 1936 style.
That was an Aveling & Porter too
