Virginian railway equipment is typically either completely generic or absolutely unique.  Virginian gondolas fall into the latter category.  The G-5 gondola was a 10-panel, 46' car, and the only accurate model is available from SunShine, a resin kit.  Older Mantua gondolas (11-panel, 40') are close enough to make an attractive, plausable model, as is shown here.
