ME 262C-1a

[pstrany]

Hi;

I'm looking for a bit of information on the Me 262C-1a (single Walther rocket engine in the tail.)
First, I am looking for a rough idea of fuel storage, and alos burn time for both the rocket and the jet engines. All literature indicates the rocket fuel was to be carried in a compination of the rear tank and auxiliary tanks mounted on the racks under the nose, but the only photos I've seem of "186" (the only example of this configuration to fly) seem to show the rocket engine running, but no tanks under the nose. Was the fuel only carried internally? What was the maximum duration of "burn" for the rocket engine? And what of the jet engines?
Next, I am looking for a picture of general configuration of the controls for the rocket engine that would have been mounted in the cockpit. I am sure this is a long shot, but it would be helpful to be able to base this on something other than speculation (and what controls and gauges WOULD have been present for the rocket engine?)
Lastly, I'm looking for the outside diameter of the rocket engine opening (I'm building a virtual model, I need to be able to proportion all this correctly.....)

Thanks!
