Scale Aircraft Conversions specializes in white metal replacement parts. Its line of replacement landing gear has been expanded to include a set for the venerable Bf-110 from Revell/Monogram.
This set is one of the more elaborated sets from SAC I’ve seen. It includes three main parts – two landing gear struts and a two-part tail wheel, plus 3 “frames” with the rest of the delicate parts.
My example arrived partially crushed (I guess due to shipping). Having the small parts attached to a “frame” actually prevented them from being distorted. But still, a bit of work might be needed to straight them out; however, it is very easy to work with white metal (check the SAC website for details).
