Nice, I don't normally check in that area so I would have missed it! That 0-6-0 looks right in line with what I'm looking at, but I'm not sure about the 4-4-0. Judging by the people standing next to it I'd guess that loco is at least a couple feet taller and has a larger boiler on it. Good info about the domes in that thread too, I had always thought the fluted domes were the older model.
 Oops, I read that wrong. I though it said the 4-4-0 was from the 1860's, not the 1890's... So I guess the fluted domes ARE older.
