No idea of actual custom fitter etc but it looks like a rectangular headlight HD type copy that a guy in Texas was selling on two eBay sites and his actual shop. Talon Billets.
I think they may been sold for R3Ts but I bought one anyway to try.

You could buy just the front batwing skin in plain black ABS plastic or ABS plastic coated in fibreglass and a finished in black polished gel coat. Theyw ere sold as is no brackets requiring a custom fit. More finished ones may have been available I cannot remember.
@Kevin frazier has a batwing he got in the USA on his R3T
At Talon Billets, we specialize aftermarket accessories for you Harley Davidson, Honda, Yamaha motorcycles and much more! Saddlebags, Handlebars, Pedal and Pegs
I bought one anyway to try about 5 years ago and tested it up fit wise on my Roadster with
@Longrider one day and we discovered that it did fit over the two headlights but I never made up the brackets.
A bloke in Wagga, Australia bought it off me a few weeks ago for his Rocket III knowing he will have to make a bracket system from scratch.
PersoNLLY i WOULD START WITH THE STOCK 4 CLAMP fork SYSTEM AND USE a THREADED TIP RODS OFF THEM AND THEN CUT AND BEND TO LENGTH REQUIRED TO FIT INSIDE THE BATWING. Sorry phat phums!
Easy enough with a 'P' clamp to hold the rod ends to the pre drilled screw fixing bosses that come inside the Batwing. You can buy P clamps or just make them out of any thin tin or steel strip tape, steel binding etc.. Once all set and happy you can use a good epoxy putty to seal the mounts all up and prevent movement.
Then shock horror..... cut hem all in a suitable place and thread each end to match a turn buckle and voila you have a quick detach system. that can have shorth fixed mounts left in the clamp or removed entirely when screen removed.
