ESU Adapter board 21MTC to Next18, for certain Liliput engines

This small adapter board is a practical helper for equipping some models (e.g. from Liliput) with a LokSound decoder: A 21MTC interface was installed there, but the required length for a LokSound 5 decoder was not taken into account. With the help of this adapter board, a LokSound 5 micro can be used horizontally in the available installation space. If the width is 21mm, these locomotives can now also be easily converted to LokSound. Dimensions with LokSound 5 micro 58818 plugged in: total width 21.5mm x 19mm length.
