B-29 Superfortress Metal Landing Gear for Revell Monogram (1/48 model kit accessory)

Why white metal? An advantage of white metal is the way it holds up under drilling, scoring, sanding, etc, as it is much more dense than styrene plastic and has a much higher melting point. Being quite malleable, it can be bent without fear of breaking and this is a useful characteristic when it comes to final alignment tweaking. Another advantage of white metal over styrene plastic is strength. Metal parts will not warp under the weight of a built model regardless of the size of the aircraft, no matter how many years it stands on display.
