Dave, FYI, shortly after the Legacy versions came out they were being blown out in the $8-900 range and then later for around $750. Just a little perspective. All of the Mohawks including the first one with RS4 share identical details save lettering. The RS4 has two chuffs. The rest have 4 chuffs and synchronized smoke. The TMCC engines have Pittmans, the Legacy have Canons. Current ebay prices are nuts.
