I am about to update and detail a lima model of 47 522. I need the following information.   What under frame tank  arrangement applies for when it was in the LNER green? Did it still have it`s boiler exhaust ports on the boiler room roof?, or had it been repaneled? When did this loco have it`s buffer beams cut away? When it was in green, what braking arrangement was it fitted with, air only or dual braked?   Cheers in advance for any of these questions you out there may be able to answer.
