A useful wood frame chassis kit from Ratios' LNWR wagon kits for wagon modellers allowing conversions and variations to be modelled easily.
Two underframes can be constructed from each pack, one set of solebars being slightly longer than the other, so take care when pairing them with the floor units and double-check the axles are square before final fixing.
Lengths can be adjusted easily by trimming to shorten or in-filling with plastic strip to make up to the length required.
