Bachmann 31-650Z Class 47 Intercity Swallow Livery Windsor Castle OO Gauge

Bachmann 31-650Z Class 47 Diesel Locomotive "Windsor Castle". I purchased this loco some time ago and it has been stored in a cupboard ever since. The loco is in excellent condition, and it was purchased in working condition, it is being sold as is, untested. When I received the loco, the body wasn't attached to the chassis and despite my best efforts I can not get it clipped back on, there must be a knack to it, so the body is not fixed to the chassis, the screws will be supplied.
