Coaler versions

Does anybody have pics of an armed Antonov AN74 “Coaler”. I remember reading that they come with the option of weapons fits but can’t remember where. Also is there a pic or any info of an AEW version that had its radome on a swept forward tailplane? I’ve taken that info from “Airforces of the World” which mentions an AN74 Madcap version similar in concept to the Hawkeye but it doesn’t elaborate as it was only a rumor at the time of publication.
