I bought this instrument from expert fettler David Robertson during 2020. Since that time I have joined a band and now no longer have the time to enjoy it in the way I want to. It is a sought-after "C. Jeffries Maker" instrument. If you watch this video, it will tell you everything you need to know about the concertina which has not been out of the house since I got it apart from one supervised trip to Martyn White to get it checked over. All buttons function correctly and it is in tune. The concertina has a lovely tone - not harsh but sweet yet still loud! I have attached the layout which David altered from one that he described as "eccentric". To be honest, I never used the extra buttons on the ends of the rows as I played it like a standard 30 button anglo. The concertina has a Bb drone on the left hand side. There was no case for the concertina when I bought it and that is still the situation I'm afraid. I have priced it to sell quickly at £3995 and I'm sorry but I won't take any offers. I won't be posting it as I wouldn't want to chance it so you would have to come and pick it up from S.E. Essex, near Southend. Payment by direct bank transfer only (no cash or PayPal please.). Due to the risk of posting I won't be offering this for sale to someone outside the U.K. Here is a link to Martyn White playing it more expertly than I could! https://www.dropbox.com/s/5pnu4qzik19ng4h/Jeffries.mov?dl=0 ...and here is a link to the original Concertina.net advert from which I bought the instrument. Lots of good photos here! https://www.concertina.net/forums/index.php?/topic/22417-38-key-bbf-jeffries/#comment-203754 Here is a chance to own a genuine Jeffries concertina at a sensible price. Thank you very much for looking.BbF Jeffries existing layout with corrections.pdf BbF Jeffries existing layout with corrections.pdf

The 'inboard' mounted reeds on the Jeffries 38 system (and presumably the larger Anglos and duets too) have a slightly different tone to those mounted at the side of the reed pan. This problem is most acute on the left side thumb button reeds, where the tone is distinctly nasal in comparison to their 'outboard'cousins. Because of the position of this button's reed chamber, the air hole is drilled through both the pad board and the action plate and is thus twice the depth of all the other holes. In a sudden fit of activity last week, I thought I'd check what a reduction of the reed chamber size might do to the tone, since I'd seen a kind of 'double wall' on the respective chamber of another instrument, and also noticed that the air hole appears to be drilled more towards a position above the middle of the reed than on other notes. Anyway, I made some experiments with modeling clay and found enough of an improvement to be worth mentioning here. The best position seemed to fill the chamber up to, and over the clamping bar of the reed as shown in this picture. I have now replaced my son's modeling clay with a piece of blu-tac which I feel will less likely to stain or damage anything. It should also harden in time and be easier to remove. I've made a couple of very unscientific recordings both with and without the modification, which nevertheless seem to bear out my audible impressions. In both recordings, the thumb button is the middle note of each descending run of three notes and I've recorded both push and pull. Anybody else tried this, or found a different solution for this problem? Adrian.
