Though I no longer have any Empires, I bought a number at one time to get complete stacks, whistles and working heaters...often sold the remnants for as much as I paid even though I honestly described item as missing X, Y or Z...could be the buyers were looking for another piece. I don't fret over breaking up a common engine...it's like organ donating...multiple recipients can be made whole again...so one sacrifice = many brought back to life.
