I saw a 1950s-60s black Locomotief 28" wheel Dutch roadster with full chaincase locked to a bike rack on Pacific Avenue in Santa Cruz CA yesterday. It was the real deal- a bit of rust, replaced saddle, mount for an over-the bars child seat, one grip missing, and coaster-brake only. One Cheng Shin and one Schwalbe tire. Cottered cranks, of course.
It looked like it had many thousands of miles on it. Apparently Gazelle bought up Locomotief in the late 60s, so it's a veteran.
Unfortunately, my camera was miles away, or I'd have snapped a shot for posterity.
