This model is the Bluebox 7433 - Copy of MB25b - Volkswagen Beetle in silver plastic.
The model has all detail cast into the main body casting. At the front the head lights have been highlighted in white. The rear lights are also high lighted in red. There is no interior or glazing. The base is silver plastic and is marked "No. 7433, Volkswagen, Made in Hong Kong" on three lines to the middle centre. The wheels are black plastic, press fitted to steel axles.
Probably issued in the 1960s, although not identified as such I believe it to be a Blue Box item, although it could just as easily be by Blue Bow or any other Hong Kong manufacturer.
