1934 Chickering & Sons 9' Grand casters

[ARTHUR CHICKERING]

Dear List,

I have a customer who is looking for casters for a Chickering&Sons 9'
Grand.  I believe the piano was built in 1934-35.  The piano was on a
piano dolly in a church, but has since been purchased by this customer.
The original wheels have been lost.  I do not have access to this piano
as it is in another state.  I was wondering if there was anyone on the
list that has worked with this piano before and might know what caster
to use?
