I have posted a little mod for Historical Gunsights for EAW 1.60 over in the European Air War download section at CombatAce, if anyone is interested. It is only a Beta, at best, from someone with no experience at modding.
I did little, anyway, and just arranged a proper folder structure. The real work was done by people such as PapaRomeo, Peregrine, Spit9, Viper, RedEyes, Lurker_HLB and others.
This mod is set up for use with the JoneSoft Generic Mod Enabler (a freely available download).
