This model is a TT120 scale body of British Railways diagram 1/110 rivetted steel 21t end-tipping mineral wagon. It is designed to fit on the 12' wheelbase 21'6" OHS 4-shoe chassis previously uploaded. Please note the brake lever with the reversing hanger should be on the left hand side of the wagon, if the end tipping door is regarded as the "front" of the wagon. Apart from the chassis, you will need wheels, couplings and possibly a cosmetic hook on the headstocks. These parts have been uploaded separately if you don't have your own spares.
