I thought I might have an easy answer for this one. The kit is still available from Revell Europe, which makes many of its instruction sheets available online. But I checked; the Bounty kit is, for some reason, one of the few that don't offer that feature.
If you don't get a better response here, you might try Revell Europe. Since the kit is still on the market, they might be willing to send you a set of instructions. Just go to www.revell.com , then click on "Europe" (near the top of the page). I'm pretty sure there's a "Contact Us" button somewhere on the site.
Sorry that's the best I can offer.
