Dear Mr. Bronc,
thanks for your intellegent comment even it doesn't help at all.
First af all, there is a part number on the part which is quite vidsible. The part number is:
R8-109.412-0101
. For the specialists in this Forum it is easy to identify. In Addition you can see some fingers at the part. So if the part would have a lenth of 30cm, how big the fingers must be? Giant fingers

Try to compare the fingers with the part and it can be max. 10 to 15cm, right?
Now, based on my Input it would nice to receive your qualified answer and thanks in advance
Rolf
