Here's another beautiful Century 21 toy car, the Vauxhall Cresta from the 1960's, which was recently sold by 'verstecken' on Ebay. It has rear wheel friction drive, chromed wheels, tinted windows, lift up bonnet revealing chromed engine and is approximately 12.5cm. The model number on the box edge is 3009-1 and on the car underside is embossed 3009.
If you look at the picture of the underside above you'll notice that the toy is actually a LUCKY car! So it would appear that Century 21 simply re-boxed it and that's it! Lucky toys also had their identical own boxed version as well pictured below.
Are there any more links between Century 21 and Lucky?
