The camera I use is bought by a well known supermarket chain. The supermarket is cheap and it is obvious the saved money by very poor interior archtecture. It is a German concept - The supermarket, not the camera. The camera is probably from the far east. It is a proper camera.
Here I have two more pics of particular frame features. The 1st is showing the cut out 'M' of Miyata the 2nd shows one of the Shimano dropouts:
The cableguides on top the bracket are Shimano too.
Another roadbike in my collection, the '91 GentsRacer Carbolite:
In the foreground the SkyExpension can be recognized.
