I am going through a similar process with Trijicon. I never received a reply from Trijicon USA, but the local Aussie Trijicon, originally asked me to measure the double rifle mounting bases or area and see if they have a model which will fit.

I know you have been trying to get onto EAW, so the best bet would be to try to deal and get information from a dealer, or distributor of the companies in question.

I can't answer which base would fit, as I don't have the double rifle in question or one like it.

Yours looks like this?

Installing the Sight on the Firearm
The Micro Sight is designed for installation on most types of weapons, which have a MIL-Std 1913 Picatinny Rail or Weaver Rail. If your weapon does not have or support an appropriate base(s), please consult your dealer, gunsmith or other qualified source.
Installing the Sight on a Picatinny/Weaver Rail
a) Loosen the Shaft by means of the Allen Wrench, so that the Locking Bar (12) can clamp around the Picatinny/ Weaver Rail.
b) Install the Sight to the weapon Rail by tightening the Shaft). First, ensure that the Sight is correctly positioned and that the Shaft (=recoil stop) fits into a groove on the Picatinny/Weaver Rail.
To make sure that the Shaft is firmly tightened, screw the Shaft clockwise until a light resistance can be encountered.
After that, screw another 1/4 to 1/2 turn. WARNING! Do not overtighten.
c) When using Lens Covers, ensure that they are correctly positioned and can easily be opened.
d) Finally, make sure that the Shaft with Locking Bar is firmly tightened around the weapon Rail.
e) Complete zeroing according to the "Zeroing" section below.
