ten quid for a concertina!

sounds like there could be 'a modest profit' -as they say on Bargain Hunt.

fifty quid would be a month of my Dad's wages in the 1960's. round about that time - i got my first guitar a Rosetti, costing 4 pounds 19/11d.

I couldn't afford a good guitar til I was working ten years later from Kays catalogue.

What learners do is their own business. What folks taking it seriously do is give it their best shot.
