What is this part?

Got a bunch of parts as part of a deal a while back. I have this which I assume is a brake and accelerator peddle assembly. But looking on eBay to price it up the ph2 172 parts look a bit different. This came from a ph2 172 as far as I know but can anyone identify?

Looks to be full pedal assembly including the brake servo and master cylinder. Havent seen one removed before so cant comment if it is definately a ph2 172 item. It is upside down in the photo though

Awesome thanks. Any idea what would be a sensible price?
