MARKERS UNIVERSAL TRUCK PROP

One of the original props on display at Smallspace was one of the three Markers Universal transporter trucks as seen in UFO.

The three trucking rigs were used in the series to inconspicuously transport the Shado Mobiles to ufo landing sites.

The miniature uses the base of a Toppers' Johnny Express toy , which also turned up in various guises in other Gerry Anderson shows.  

Here's the Markers Universal transporters in action.

I believe it's current owner is Mr James Winch, the chap responsible for restoring the Shado Jeep.
