Not quite .....brand new plastic Hornby repro wheels are available from Stuart Metcalfe @40p each and suitable axles from Tony Funnell at about the same price .....and both are very good ,producing smooth and free running vehicles . I buy both by the 100s for my own use ..hence being a bit vague on current prices.
Wooden ,litho covered wagons is *coarse modelling * at its best/cheapest/most fun !
If you want to go for 3 links, Amberley Services supply sets which are not too fine scale and well made , I think their price is about £4 50 a set .
Tony also makes new Hornby tinplate wheels as well ..but says nobody seems to buy them .....Bruce
