This is for an ESU Loksound Micro 8 pin 97817 sound decoder loaded with the Pannier GWR Group 1 sound project from South West Digital Bought new by me a few years back and never used. Speaker is simply taped together with insulation tape (not glued) so you can hear it working properly. Decoder has been tested and works exactly as it should plus I've updated its firmware to the latest version so as goid as new. Comes with the SWD instructions and original ESU packaging.
