LMH06. A very good kitbuilt model of a Single Car Class 121 ‘Bubble Car’ Diesel Unit No. W55023. This is very well built and fitted out and finished in BR green with yellow warning panels, possibly from a Westdale kit if they did one (but it is certainly from a metal kit). With Wayoh bogies. It has a twin shaft motor driving both axles on one of the bogies. It also has lots of underframe detail. The model is lightly used. I believe the prototype is preserved, possibly at the Chinnor and Princes Risborough Railway where it was active a few years ago. £350.
