One example was presented in Concertina Magazine No13 (1985), on the cover and page 2.
A Wheatstone English number 28438 with two reed tongues on the same frame.
Nothing said about the tuning but since the tongues have the same length it probably was "wet". The ledger - 10 June 1920 - only says "Special"
Hi Folks
Came upon this thread by chance and thought I would let you know that 28438 is now living comfortably in South Australia. In good genral health, no leaks, worms or rot but a little out of tune.
I aquired this instrument of pleasure back in 1984 from Dave Bryant in London, in pieces at the time, the size hinted that it was a bass, I had no idea about the details of concertinas other than I had seen Mike Harding playing a bass and I liked the sound. Shipped the bits back to Oz and Richard Evans ( Concertina Magazine) refurbished and tuned to something useable. Since 1986 it has been relaxing, unplayed but not forgotten. I have no record or information where it has been or what it had done between 1920 and 1984 so if any one has any info it would be appreciated. A phot sessio has been organised for the afternoon of Friday 20th Jan and I wil post the pictures on this thread as soon as I can. If anyone has any special requests for photo angles or poses let me know
Cheers
Tony
