12 x Hornby Dublo 3 Rail Metal Wheelsets. Measure 15mm across the wheel flange, 12mm across the wheel tread and have a 26mm axle length. In usable condition, but have some surface rust and dirt so would benefit from a clean up. The ones I have left in stock are on average better than those pictured. They are the later sintered steel type. Please have a look at my other auctions for similar items, postage gladly combined on multiple wins. Postage offer - when invoice is combined, only pay the P+P on the biggest or heaviest item. Any other items travel free with the first, as many wins as you like, including international buyers. There's no rush to pay if you are bidding on my other auctions, but for those that are ready to pay for multiple items, postage discount is automatically deducted at checkout.
