REQ - Permission for use a guns library

[VonDos]

Hi everyone!
While finally testing RM Aquila new carrier, i've readed original project's specifications about guns:

MAIN --> 8 × 135 mm (5.3 in)/45 cal guns
SECONDARY --> 12 × 65 mm (2.56 in)/64 cal guns
A\A --> 132 × 20 mm (0.79 in)/65 cal

At moment ingame model use as secondary guns 4.0 in. single from standard guns library. Powerfull. Too powerfull in place of a 65mm cannon.

I've searched into my library folder a more "historical" or similar gun, i've found "76mmRSingle" from gunsVaa_Liliput.dat, i think from "Vaa_Liliput"
I've searched this member but i can find he, for ask permission to use his guns in final release. Does anyone know how to contact him for ask?
Naturally if ok for him, i'll give credits
