The little girl's pram is clearly modelled on a full-size pram, the adults looks like an in-between pram/push chair, the push chair, like most modern buggies, putting the child in a sitting position. (I suspect that the back of the larger pram can be swung down).Two prams of the type which have gone out of fashion show in the old photo and other items but it was 70 years ago ...
My sister had a high-quality toy push chair that might have been made by Pedigree or at least under licence to them. I got great pleasure by folding the hood and handle down and pretending it was a train. The pavements by us were in a 2/3/2 slab pattern, giving three crack lines along the length, dividing the pavement into four tracks, the outer 'slow' lines and the inner 'fast' lines. Simpler times when one had to use one's imagination!
