The plastic actions made for Fischer, Chickering, and others were made
by Pratt Read, and yes, the jacks, backchecks, damper levers and
flanges and also butt flanges were plastic.  Yes, any plastic should
be replaced.

The Conover of this age I have worked on only had plastic flanges.
Yes, I would like to replace all the action parts.  The cost of this
work would be 3 to 4 times the estimate quoted.  I have not seen the
instrument and could not say if the hammers and dampers are not usable.

New parts are seldom the same as the old parts in actions of this type,
and the time to re-regulate these [new] parts I have found is very time
consuming.  The cost of complete replacement of wippen, butts, hammers
and shanks, also dampers, lever flange and felt, and then adjusting and
regulating, would put the repair at a level of a medium-cost new
instrument.

As a technician I would have to explain all the possibilities to this
customer.  It would come down to the value of the personal attachment
the customer has to this instrument.  In the market today the old
instrument value and repair is still at a disadvantage to the Asian
instruments.
