Eberhard,
I can tell the results of compression test :
1: 140
2: 140
3: 150
4: 140
5: 150
6: 145
7: 145
8: 150
Not sure how I can read that with your 8.0 :1...?

It is also not clear to me where this "Japanese sign" should be founded...First crossmember..? Please, help !

Don't think I'm stupid...just try to understand! Thanks,

Pierre
