One pack of Howes replacement wheelsets for HeljanClass 47. These were briefly fitted and used but I am now disposing of much of my fleet so no longer required. The pack contains six axles, four with driving cogs and two without. Now adopted as standard by Heljan , these packs vastly improve the pick-up qualities of earlier Heljan 47s compared to the original wheels.
I believe that they are also suitable for Heljan class 52, 57 and 58 locomotives.Best of luck with your bidding !
