I think it's an '87. It does look Ironmanish. '87 Ironman Master color way, '87 Ironman Expert style frame, '87 Ironman components, '86 Ironman style forks.
The solid white forks and chrome chainstay are Not Ironman like.
The seatstays are different from the Ironman expert frames and the brake bridge isn't on any Ironman I've ever seen.
Sorry I couldn't help with info on Your bike but I like it.
