david robertson Posted December 29, 2019 Share Posted December 29, 2019 I have a Jeffries Duet coming in soon for restoration, but it's the first of its kind I've tackled in 15 years, and I'm not familiar with the layout. Does any kind soul out there have a diagram that they would be willing to share? Link to comment Share on other sites More sharing options...

Does any kind soul out there have a diagram that they would be willing to share? The diagrams are variable depending on the number of buttons, the amount of overlap, the core key, the choice and placement of the lower notes and how the sharps and flats are arranged. The core seems pretty consistent though. You can find Nick Robertshaw's diagram for his 51 button as well as a pattern for a smaller box by googling Jeffries duet finger patterns. Polly Clapp shows a diagram for a 58B in her article in Concertina Journal. These 3 examples seem to represent a loose standard although of the 6 or 7 I know of the only match is my 51 and Big Nick's. Additionally, Crabb, Wheatstone and C.Dipper made examples ( as per Polly Clapp) and I can vouch for Crabb and Wheatstone using slightly different set ups.

saguaro_squeezer Posted December 30, 2019 Share Posted December 30, 2019 I have a diagram but it's probably the same as Polly's. I'll send it along if you'd like, David. Link to comment Share on other sites More sharing options...
wunks Posted December 30, 2019 Share Posted December 30, 2019 Squeeze, I have your pattern (for which I'm grateful) and it's a B flat core right? Link to comment Share on other sites More sharing options...
gcoover Posted December 30, 2019 Share Posted December 30, 2019 Hi David, Excellent news! There weren't that many Jeffries Duets made (maybe 200-300 max) and some have been re-reeded to try to be Anglos, so it's good if this one gets to stay as original as possible. Attached are a couple of charts for 50 and 60+ buttons in the key of C. Lots of variation in the larger sizes. Would love to see a photo once you get it in or when all fixed up. In related news, I'm getting really close to finishing a Jeffries Duet tutor with over 60 tunes, from super easy to really difficult, including several tunes from "The Rampin' Cat". Can Jeffries Duet World Domination be far behind?!? Gary JEFFRIES DUET-C-50.pdf JEFFRIES DUET-C-61-62.pdf Link to comment Share on other sites More sharing options...

david robertson Posted January 4, 2020 Author Share Posted January 4, 2020 Just when I thought I'd seen it all... the 'Duet' turns out to have been converted from a 38k Anglo, with bits of fretwork removed to make way for extra buttons on the innermost rows. The air-button hole has been blocked up, and new inboard reed slots routed out where it used to be. I've seen Duets converted to Anglos, but this is the first time I've seen one switched in the other direction - a bit of vandalism that I imagine has knocked the value back by 75%! 2 Link to comment Share on other sites More sharing options...
gcoover Posted January 5, 2020 Share Posted January 5, 2020 This must be one of the ones Jim Harvey referred to, mentioned in a previous cnet post, talking about some folks converting from Anglo to JD back in the day. But you're absolutely right about what it did to the resale value! Gary Link to comment Share on other sites More sharing options...
Robin Harrison Posted January 6, 2020 Share Posted January 6, 2020 Does it make any sense to return it to an anglo ? Robin Link to comment Share on other sites More sharing options...
david robertson Posted January 6, 2020 Author Share Posted January 6, 2020 It might do if one had a supply of spare Jeffries reeds... and a pair of non-mutilated Jeffries ends! Link to comment Share on other sites More sharing options...
