What did you do to your trains today?

One of only a few versions I've seen where only the firebox is changed and his parts are not transferred to a repainted Gordon (though the latter way to do it fixes what the TV version did wrong). Will the rest of him be repainted, or will you match the firebox to the original shade? I shall be happy to see how you'll handle it.

Also, I'll guess Edward's coupling rods will be used to convert an engine with faux rods (Skarloey or Peter Sam, perhaps?) if not a scratch built engine. Correct?
