From what Oxford Rail's website has said they do intend to do a number of versions beginning with the GER and early LNER versions then following with the later round top versions, I do think it's good to get a GER liveried loco though it's different and I think all the models will sell well.
The artwork for the model looks fantastic, eastern region modelers have been very lucky the past few years, just hope that a GER T26( LNER E4), J17 and BuckJumper J69 will be made. But that's hopeful thinking
