My apologies for not replying sooner.
I have been made aware that the instrument is not a 'garden variety' one, The gentleman who repaired the instrument offered a tidy sum for it before undertaking the repair.. but I do not know the nuances and eschelons of the concertina world - I'm a pianist first, guitarist second and a hack concertina player in dead-last
I have to admit this one is getting the better of me, dare I say it, if it had been passed to me a couple of decades previous I'd be a far better musician. Boy these things do my head in.
My uncle & cousin both play accordion, one more proficient on the buttons, the other with the piano keys - So I am learning, but the concertina is certainly proving a challenge for me.
I should ask the wider audience if they had an 'easy run' or if they too found learning difficult. Perhaps there are techniques I am unfamiliar with that would make me a more competent player? I basically have copies of the old lachenal manual, and from what I interpret through my hack playing, is that these are quite a modal instrument with regards to the fingering arrangement - but (excuse the pun) I am trying to get my hands on it - the grey matter is somewhat slower to catch on though.
