(picture)56 tone ,28 keys Konzertina "Uhligs"1840
lay-out dating from probably the 1860`s )

coll.Mr.Stephen Chambers
About the mid 1840`s two more
modified Konzertina lay-outs are worked out by Mr.Carl Zimmermann (produktion of
Carlsfelder Konzertinas since 1849 at Carlsfeld/Germany )and Mr. Heinrich Band
from Krefeld/Germany.
They must have heard about Uhlig`s instrument
.
Mr.C Zimmermann and Mr. H Band were musicians/teachers, and they seemed to have
disliked the small range of Uhlig`s lay-out.
Separate from each other they made their modifications.
Zimmermann`s lay-out became known as the " Carlsfelder Konzertina",
and Band named his instrument after himself " Bandonion".
