How many 747-200 are still in service? I'm wondering how many 747-200's are still in service?
I know for sure Rolls Royce is using one for testing purposes.
And the one from the US Forces.


Are there any civilian operated ones left? 
Does somebody have photos?
Running the numbers from RedGrittyBrick's answer, there appear to be 36 active 747-200s out of 393 built (according to Wikipedia). Of the 36, 9&nbsp;are passenger planes, 22&nbsp;freight (including 6&nbsp;converted from passenger planes, marked *), 3&nbsp;combi (passenger and freight), and the two VC-25As ("Air Force One").

The active aircraft are as follows, with tail numbers included so you can look for photos.

There are also several stored aircraft, including the Rolls-Royce test plane you mention in the question.



Thanks to fooot for explaining that BSF denotes "Boeing Special Freighter", a passenger plane converted to freight use.
