WPS18. BR Departmental Twin Jib Track Laying Crane Unit No. 78212. The model is believed to be from a GJH Plant kit (of which I have no details) and is lightly used. The prototype was a Heavy-Duty Self Propelled Twin Jib Track Relaying Crane, built 1977-1980 by Plasser and Theurer (but note that the model is not propelled). It was originally numbered DB969045, later 78212 and DRP78212, and the TOPS code is YJB-P. There was a sighting of it at Princes Risborough in 2020 so it may still be in service. £175.
