Scale Aircraft Conversions specializes in white metal replacement parts. Its line of replacement landing gear has been expanded to include a set for the Trumpeter Vampire.
The set includes 4 parts, two landing gear struts and a two part nose wheel, finely molded in white metal. These parts are drop-in replacements for the plastic parts.
You can see from the pictures the parts are very cleanly molded and formed. In particular the nose wheel replacement is more accurate is it includes a missing oleo (as you can see from the completed model, which was built using the plastic parts).
