Hello everyone

I'm an absolute fan of the different EK business class cabin designs of their 777. When searching the web I noticed that the oldest 777 A6-EBU and EBM seem to have the wide wood trims around the windows plus electric window blind.
The slightly less old A6-ECA,ECE...ECK seem to have the narrow wood trim and manual window blind. Allthough: I found images of ECF and ECG with wide wood trim and electric window blind. Could be mistakes?
Then again, A6-ECO to ECZ and newer seem to have the wide wood trims plus electric window blind (the design I like most, contrary to most other peoples taste I guess).
Does anyone have a complete list? I saw an excellent spreadsheet already, with details about the different seats in business class. It's even up to date which is outstanding. Excellent job!!
I tried to post this with images earlier, but as I am a "newbie", probably that has been rejected due to the links.
Sorry for possible language inaccuracies.
Any hints would be appreciated.
