Greyhound Super Scenicruiser bus.

Express, 554Z.

Blue, white and silver. 

Plastic main body and metal baseplate.

Scale: 1/43.

Date of manufacture: unknown.

Made in China?

Loose, unboxed. (No box).

Some damage.

No wing mirrors attached to the model. One is broken and included. The other is missing.

There is a very small stump where one was and a scratchy patch where the other was. 

There is glue around one of the fittings for the wing mirrors. This spreads over the bus and the window nearby.

Two of the side windows are loose and not sitting in its correct position. There is movement here, but they appear to be held by a fitting at the top of the pane. 

The paintwork on the main body has only minor marks etc...

The windows have some marks, scratches and scuffs.

Two sets of wheels turn well. The set just before the rear wheels are a bit clumpy and do not turn as freely.

Approximate dimensions: 28.2 x 5.5 x 7.5 cm.
