Riser with shelf on opposite side?

[Brandywine]

Hello:

I have not posted here for a long time and while still active casually, am not hunting.  Twangs of nostalgia gripped me and I recently got a new set of ACS  Iongbow limbs from South.  Happy to hear that all's well there and with Larry.

Anyway, was scanning longbow risers and saw a G-10, right hand with right SHELF. I cannot recall such a configuaration.
Considering the amount of work, it can't be a joke.
Would appreciate someone pointing my brain in the right direction, please. Thanks.

All the best,
Kevin Tinny

Right handed shooter would need a right side shelf when shooting with a thumb ring.

Thanks, Pete:
For some reason the thumb ring went through my brain and I ignored it.
I think Hanify might use one. 
Great help.  Will skip the imogee's.  Afraid I'll select something "odd".  Haha.
