This is a pair of bufferbeams designed to be glued onto the inner ends of the Dapol FEA-B Spine Wagon double sets. This is to convert them into FEA-F single wagons so that the loco hauled Royal Blue "Splash and Dash" Rail Head Treatment Trains can be reproduced in model form. Using them will require a modification of the inner end coupling system to lengthen them. Suggested material is FUD. Fettle and fit the couplers first then glue the buffer beam on.
