I understand all that, but we (or at least I) was discussing parts which 
are in current production for current models which are identical to parts 
for older instruments which have gotten misplaced from their original sale 
market for whatever reason.  (I know servicemen and women buy things 
overseas and occasionally bring them home.)

I would think that these quality parts, such as dampers, which are in 
current production and thus would have minimal, if any, tooling costs.

I know from my textile machinery manufacturing days (very small company) 
that estimating necessary inventories of replacement parts for normal wear 
is dance with very fancy footwork, but with the millions of units which 
Yamaha has produced in more than a century, there should be a VERY solid 
statistical analysis possible.
