I will clarify my earlier posting. I started off with a G/D Hohner 20 large white button Anglo. I purchased it to see if I liked playing the instrument £10 and for nearly two years it was exactly what I wanted. It played in tune with the other instruments . It was perfect for Morris Music playing ,after being thrown into the deep end when no musician turned up to play for the dancers, I had to play solo. Brian Blanchard was then a member of Broadwood and he had a Jeffries and after playing his a couple of times that was my ultimate aim. My second concertina was a thirty button Jones in nice condition, but a bit out of tune. On approaching Crabb Concertinas to get an estimate of its tuning I was offered the Jeffries in part exchange (plus £125 )and that is how I acquired my CG.
So for a time The Hohner was my favourite instrument based completely on cost and my learning curve (which still continues).
