Grab Rail Identification

Any ideas what this should fit?
Taken off my new to me 2012 Bonneville SE

the rear 4 mounting points Were in the right position and had the four bolts connecting it to the frame , but the front arms were sitting down below the level of the rear shock mounting points , so were not connected ...

 

Thanks for that... it’s no good to me so I was going to advertise it...

 

I know it wasn’t definitive

I think it will be hard to identify without someone who has had the same issue and solved it....It’s going to end up sitting in the garage...suppose it would work for a Bonnie if the ends were cut off and blanking bungs fitted.....it was pretty solid with just the 4 bolts holding it under the seat..

it’d look quite neat
