Hi OldNoob, hi Cap,
IMO the easiest way is to contact Revell directly, email the famous "Abteilung X" and tell them which parts you need (part numbers from instruction will be needed). They will help you. A friend of mine "destroyed" the "Balkongeraet" of his typenine-kit. It took two weeks and Revell provided him with replacement parts with no charge. Don't know how will be if you live outside Germany but it will worth the try.
Regards
