help with crash bars

[Brc]

Hello,
firstly I'm sorry that I don't speak german, but I have no one else to ask, and you are perfect to ask for a BMW help.

I have bought crash bars at Milano and italian guy screwed me. He said that crashbars were for 1200 GS model but they dont fit.

I have tried to put in on this models and it dont fit :
BMW R 1100 R, R 1100 RT, R 1100 GS, R 850 R, R 1200 GS, R 1150 GS, R 1150 R

If someone knows something about crashbars please check my photos and help me for which models my crash bar is.

Thanks in advance,
have a nice holidays!
