Well, if you want to wait over a year by accounts! (People in Europe can send headphones to Oratory, and I think he said he sometimes receives them Internationally too).well if you want a certain product to be measured, your best bet is to buy it and send to Amir.
think about it this way: you can easily find a FR chart for ER4SR/XR/ER4S because it's a popular model and nowadays there are a handful of IEMs reviewers who have rigs and are knowledgeable enough.
models like this one on the other hand, I guess that you won't find its measurements anywhere else on the internet, if the owner hasn't sent it or Amir just discarded it.
