(See attached image) A quick plea from the C & R Dipper & Son concertina workshop:
Who ever is 'wonking' these springs and ruining them in the delightful misbelief that a super-light action won't leak, will you please stop!
This is the second instrument we have had in recently, where almost all the springs which were in perfectly good condition, will now need to be replaced, due to the spring-wonker's antics!
