I don't know what version I have. It is a 17 inch and doesn't have any cut outs in the riser like the new ones do.
As for getting hold of Mr. Morrison, I have had trouble doing so. I have sent him 2 or 3 emails asking basic stuff and haven't received any replies. I don't want to call the man and bother him while he's working, so I'm kinda stuck and have to ask questions on other forums of other ILF riser shooters.
Maybe it's because I bought it used, from someone that bought it new.
Kinda disappointing.
GREAT RISER though.
Not implying anything at all, just what I have seen.
