N Scale 8 Bridge Shoes #4

Model of 8 bridge shoes, or bearings, in N scale. Bearings allow flexing, expansion and contraction of the bridge under all weather conditions and loads, by allowing a little bit of rotation. These shoes were inspired by the ones used on the 1931 B&O Harpers Ferry Bridge.
This model does not actually allow rotation. Each shoe is 3.6x5.3mm and 5.1mm high.
