Chris Algar, Barleycorn Concertinas....

OP didn't visit this forum since May 18, 2018...

Mission accomplished...

So not at all a silly question....

"When I hover over my 'mugshot', I don't see that "message" button,....." Do you mean what you say? You're supposed to use the 'mugshot' of the member you want to send a message to.

But it is only one. Typical for Rob Harbrons arrrangements on the concertina. For example:

But this is not the definition Wim Wakker uses for his "Soprano". From https://www.concertinaconnection.com/wakker english.htm : Model W-E4 The W-E4 is a 42 key soprano model, measuring only 14 cm/5.59" across. The layout is identical to a tenor english (minus the top 6 notes), but sounding one octave higher.The sound is bright. Standard configuration W-E4: .... - 42 key soprano, from middle C to C. .... But OP's question was not in the first place about the Soprano definition. His concrete question was: Are the "on the line" notes on the left hand side? A (extended) treble has the 'on-the-line' notes on the left. A tenor has the 'on-the-line' notes on the right. So a tenor sounding a octave higher has the 'on-the-line' notes on the left, just like a treble. Am I right?

In that thread of May 2007 "the different types of English" which Genepinefield refers to Geoffrey Crabb said: "..... Just to confuse things a bit more, the 56 Treble, when it appeared, was originally referred to as 'Soprano' to distiguish it from the 48 Treble. ......"

In what price range are these plugs?

One 'a' too much. Should be: http://www.thefolkmusicacademy.com/robharbron

For some people knowledge is not based on theory, but mostly on experience. For people whose knowledge is based on theory it can be hard to believe there isn't a hidden theory. But that's just my experience....

There is no instrument for sale. OP said he wants to buy a Kensington C/G.

This might partly be caused by your own development: after these 2 month your body, your fingers got somewhat used to playing concertina, and so became more relaxed, less convulsive.
