OO 272, Tri-ang Jinty 3-Rail Conversion from eBay

Welcome to my two hundred and seventy second video on my work with OO gauge.
This video will feature a Tri-ang R52 model of an LMS 3F Jinty tank engine, converted for 3-rail running - by someone else, not by me... I bought it on eBay already converted. The video will follow my normal form: a bit of background history, a look at the new model, with some necessary servicing and repair, and some running video on my Hornby Dublo 3-rail table-top.
As always, if you have any questions about anything that I say or show in this video, or you would like more information about anything, please post in the comments below, and I will try to respond.
