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.

A picture or three will likely help here. – Ken Hiatt May 28 '13 at 20:58
how do i add a picture to this thread? – doug May 28 '13 at 21:22
I'd place it somewhere in the 80s or maybe early 90s. Not a high-priced bike, though not a real cheapie either. Maybe a brand sold at discount stores. The frame is nicely lugged. Can you make out a brand stamp on the derailers or the levers? – Daniel R Hicks May 29 '13 at 15:52
Does it say "Kontroll" somewhere else than in the third picture? Because there it stands for "control number" (used for guarantee) – unor May 30 '13 at 11:02
I think this is a Kondor frame. It was a german manufacturer see here: – Tobias Jun 27 '13 at 8:11

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:
