Unfortunally, I drop one of the two Telefunken E88CC's on the floor... and make some photos of it.

 The original TFK diamond logo between the pins. I have rasped one of the pins to see is all of gold or gold plated:

 And removed anodes - you can see very nice golden or gold plated frame and grid. I have another TFK E88CC, but it is with white frame. It is interesting to me is it also with gold grid, but wont't brake it...
