Old Delivery Bike

This old bicycle has seen better days. A lot of us will remember them. Sturdy, heavy, no gears, and rod lever brakes. Tough work for hills and into the wind. Now just collectors items, museum pieces or a prop for a costume drama. Personally I'd like one but in working order. The postman / postwoman's bicycle delivery bike has recently been phased out.

Will delivery bicycles make a come-back? Just like the way trams returned to our streets after 40 odd years.
