Perazzi Add On Rib

maybe some of you could shed some light on this.
Received this Add On Rib with a purchase of a TMX. Measures 31”.
Cannot find reference on web. Perazzi logo. But?
Seems excessive for an ultra high rib on a top barrel that has a high rib already.

 

I have a TMX, to me something like that would be over kill or not needed for any reason ... Could it by chance be a replacement rib ..? WPT ... (YAC) ...

 

It appears to have been mounted by 2 owners back.
The previous owner did not shoot the gun.

As suggested in another string, I have put the question to Phillip Crenwelge as well.

Thanks for your reply.

How do you have your TMX set up? As far as POI?
It has an IM choke screwed in it.

I am not a fan of choke tubes, mine measures .036 restriction ... I have an adjustable comb and have it set so the gun shoots 80/20 , normally I like it a little higher but this works ... 90/10 or 100% high is what works best for me ... WPT ... (YAC) ...
