Hi all, I'm looking for some assistance. I have just bought a second-hand OOP Forgeworld Cobra (type I) super-heavy which I thought was complete. When it arrived, it was missing two of the fins running round the barrel of the d-cannon see pic:
Obviously I'd like to replace the missing fins and am looking for suggestions of how to do it. Plasticard is one option, and although I could shape some pieces to match the profile, they are actually not flat pieces on the plane shown in the pic. I've not yet done any casting and wouldn't know where to start (not to mention the issue of IP etc).
Any advice is gratefully received!
