Now THAT'S a name I've not heard mentioned for yonks, Colin Burton.
When I was a [very] young lad he was one of a few "milkmen" who delivered on our estate, using a horse and cart. I remember him starting to deliver milk in bottles as opposed to the churns, but he always kept a couple of churns on the cart for the "oldies" who still went {or left out} jugs for their milk.
The house opposite ours was his tea call, whilst he was in their it was my job {and my younger brother's} to try to prevent the horse from eating the tea calls privet hedge, this was done by feeding the horse with copious amounts of bread.
and yes the bucket and shovel was on standby at our gate {great on rhubarb}
