I've just stumbled across one on page 410 of the Force And Destiny Core Rules, too.

The stats are different.

The OaA1 version is generally weaker in attributes but packs a bigger weapon and inflicts 15 damage if it self destructs.

The FaD version has better scores for Cunning, Soak and Wounds but only deals 10 points of damage when it blows.

Good to know there are officially different types.
