Tidder 20 Button Anglo Concertina 1890's? Rosewood

For sale is a most excellent Tidder concertina, 20 key/button Anglo model.  It is Rosewood ended, and has a six fold bellows, in the keys of C/G.    Steel Reeds, recently restored, with new pads and many of the valves(the ones that needed replacing were replaced!).  Sturdier construction than the average Lachenal Concertina.   New Handstraps.  Concert pitch.  Thanks for looking.
