Following the last News item I have looked more closely at the Jouef tanker that I bought from the model shop. In fact I bought another wagon from Jouef the last time I visited which when I looked more closely on the underside had Jouef for Playcraft moulded in the plastic. A quick check on the tanker showed the same thing, So Playcraft with Peco type couplings ideal for HD except that they are HO and not OO scale. The history of Playcraft shows it to be very low cost system which did not last for very long but that their are still some enthusiasts with a collection of them . Well worth a look to add to your knowledge of the history of toy trains in the UK.
