Size of pins for Steinway B

[John Delacour]

A pianist in South America has ordered bass strings, wire etc. from 
me for a 1958 Hamburg Steinway B.  He also wants wrestpins.  He has 
had his tuner remove a pin and has himself taken careful measurements 
according to my instructions, from which I can be pretty sure the 
original pins are 7.20 x 60.  Unfortunately I am not there to judge 
the feel of the original pins.

The piano looks, from many photos he has sent me, to be in pretty 
good shape and the original bass strings are made in the old fashion, 
with whipped ends, which suggests to me that things were still being 
done properly in 1958 and that the chances are the wrestplank is also 
good.

If I had the piano here I might decide that a jump to 7.25 mm pins 
would be adequate, but for safety's sake I am inclined to send him 
pins of 7.30 mm.

What do you think?
