David Peacock published a centenary history of the Leeds Model Company, founded in 1912, last year, including a cd so you can view or print photos of the company's products on your PC in colour. I jbnow, living just down the road from David, that he still has some copies left.
LMC or Leeds as it is usually referred to in the UK, was the third largest maker of 0 Gauge trains after Hornby and Bassett-Lowke. The one thing they produced that is much admired now is a range of strikingly authentic little tank locomotives, all made from standardised tooling but nevertheless most realistic. Since they never offered a clockwork version, and permanent magnets were practical by the 1930, the mechanisms were small enough to allow low boilers - typical of small British locos until the turn of the century.
Leeds also produced a nice range of eight private owner open coal trucks, again with coloured lithographed paper sides, and several classes of tender locomotives, usually based upon those of the Great Central railway, later the London & North Eastern Railway.
