Hi all, new here but have aquired a Barnet Samuel 48 button Concertina which internally is very good but both the fretted end plate covers are beyond repair due to fretwork damage (most missing).. I am sure its a Lachenal and am looking for a pair of covers to replace them but cant find any suppliers of these second hand.. Can anyone suggest where i can get them from.. Its number is 28746.. Thanks for any help... chris..
