Here's the answer according to Jentz...
'The headlights were removed, the driver's hatch was replaced by a radio operator's hatch, and the shattered loader's hatch was replaced after Fgst.Nr.250122 was captured by the British.'
I had a book from the library that covered that tank from before, during and after capture. I'll try to find the title.
The above quote (and your pic as well) is from 'Germany's Tiger Tanks. D.W. to Tiger I'
