Try contacting Dragon USA, the US distributor for Hasegawa. Search their website for a contact email address or how to obtain spare parts. Absent any luck there, the Hasegawa Leopold kit appears to be readily available on the web at various hobby websites. You may have to pony up the $20 or so and just buy another kit. For styrene to make parts, try the modeling section of your local Hobby Lobby first (if you are in the USA). I think they stock a selection of styrene sheets, etc. On the web, micro-mark (http://www.micromark.com) has a wide variety of plastic stock available. HTH.
