DeAgostini’s (Model Space) version of the Monobrake , International Rescue’s search and recovery vehicle.
The Monobrake is used in the episode, The Perils of Penelope to enter the Anderbad Monorail Tunnel and search for the missing Lady Penelope and friend of International Rescue, Sir Jeremy Hodge.
The Monobrake is a low slung vehicle which allows Monorail trains to pass above it. It carries a telescopic arm which can extend and attach to the overhead monorail. It is powered by a rear jet engine if suspended or a gas turbine on the ground.
The vehicle does make a couple of cameo appearances in the episodes, Cry Wolf and Security Hazard.
As usual I’ve given the model a little light weathering and as it’s an open cockpit I’ve done a tiny figure of Virgil at the controls (There’s not really enough room for Gordon as well)
