The Dapol O Gauge 7S-010-004 is a detailed 1:43 scale model of the London, Brighton and South Coast Railway (LB&SCR) Class A1 "Terrier" tank locomotive. Runs well both ways ,very quiet,good on slow speed.The Number 57 plate that go on the side of the cab I have lost one other is in small pkt.Sprung buffers are fine as are the links,in all a good clean engine that is hard to part with.
