gavdav Posted February 22, 2010 Share Posted February 22, 2010 (edited) Having tinkered with my two "AG duet" anglos for a while now I'm settling on the earlier conclusion that these are in fact Jeffries System duet concertinas that have been converted to anglo setup. I've come to this conclusion, eventually, based on some hand scratched marks in the nickel plating on one end of my G/D these read FGCDF GBCEGG ABDFAB CDDE and right hand (incomplete, but looks like a match to me...) AGCD BC I also have an Fsharp/Fsharp drone on the end of one row on the left hand. I compared these to Nick Robertshaw's Jeffries Duet layout diagram. http://www.concertina.info/tina.faq/images/finger2.htm Whilst it is obvious that the original owner of my box hasn't marked sharps or flats the match is pretty convincing. This looks like good enough evidence for me that the G/D at least has been thoroughly retuned to its present format. I am curious as to how many Jeffries Duets Wheatstone made and if any survive. Any thoughts? Edited February 22, 2010 by gavdav Link to comment Share on other sites More sharing options...
Greg Jowaisas Posted February 22, 2010 Share Posted February 22, 2010 I have seen a several "A.G. Duet " designations in the Wheatstone ledgers: http://www.horniman.info/DKNSARC/SD02/PAGES/D2P0140S.HTM http://www.horniman.info/DKNSARC/SD02/PAGES/D2P0850S.HTM That designation is quite rare. I've wondered if it was for the Jeffries duet system? Greg Link to comment Share on other sites More sharing options...
gavdav Posted February 22, 2010 Author Share Posted February 22, 2010 (edited) Hi greg - there's some discussion of this in two other threads - Steve Gardham's "Wheatstone Special/Largest Anglo" thread and I tried to dig up more info on A.G. Duets but nobody really bit. (both in the concertina history folder) The two large ones - the a.g. Duet and a.g. Octo on this page are mine. http://www.horniman.info/DKNSARC/SD02/PAGES/D2P0500L.HTM Edited February 22, 2010 by gavdav Link to comment Share on other sites More sharing options...
