Why would you think they had been  designed  for  A435 most straight
strung pianos )Birdcage)  were made by a few makers and shops put their
own name on

1877    Collard's piano maker standard pitch was A 449.9
1877    Chappell Pianos A455.9
1877    Mr Hipkins piano tuner A448.8 (Broadwoods )
1879    Erard's factory fork 455.3
1880    Brinsmead, Broadwood, and Erard used a pitch of A455.3
1885    At an international exhibition of inventions and music in London
a pitch of A452 was adopted.
