What bike do I have? I have recently purchased a bicycle from a second hand shop. It seems to have all sorts of different parts. The frame however has a badge and markings of 'Kontroll' made in West Germany. Doing some research I can't find anything about this make, is anyone familiar with this brand?  

As it says West Germany this may date it to the 80's. It's a large frame which is handy as I am 6ft 6.
That bike is a Swabian brand from Konrad Kotter (who had until 1982 and again in 1987 the professional racing team Kotter's Racing Team) that later went over to Albuch

The Albuch Kotter logo now looks like this:
