Someone has to be first!!!
I have Lode Star and KOGC, have dismantled KOGC to facilitate removal of moulded hand rail with minimum disruption to lining/paint. Tried it out on old model Hornby Castle cab first, easy to do if you have a steady hand. The footplate assembly is removable with care, exposing the splasher /nameplate assembly which is etched brass, once again easier to upgrade. The separate footplate obviously is for later versions with the "vauxhall" piston valve cover. The footplate is as straight as a die, no banana tendencies.
Front bogie now has 10 spoke ex Castle wheels awaiting replacements, tender is exquisite, but beware very, very fine fittings, to offset tis the brake pull rods/brake shoe clearance holes are much easier to negotiate. Paint /moulding marks along boiler top, but careful scraping, burnishing reduces there, I am gong to lightly weather the top surfaces so thought this worth the risk. Accessibility to the outside steam pipes enable the inevitable flash marks to be remove, safety valve removes easily for any changes,
All for now, nothing serious apart from bogie spokes, but I am not touching Lode Star, that is a thing to be admired!!
Had hoped to be able to provide photos but pressure of domestic responsibilities have put that off till next week
All in all, apart from the spokes, nothing that a steady hand and patience won't stop a very good model being even better, but this is the fun of Modelling, criticism is so easy, remember when Hornby Dublo Castles were the bees knees?
