Hello Members A customer has a Kranich & Bach grand c. 1902 that needs everything. The backchecks are the same as any typical vertical piano...that's just as you picture a vertical in your mind, with no buckskin over the felt. The ends of the hammer tails are wrapped with buckskin. The action is so far out of regulation the hammers won't check, so I can't gauge the affectivness. The customer wants the piano to "work" and is not concerned about preserving anything historical. Has anyone converted one of these actions to the usual grand back check and hammer tail? Other than the above arrangement, the action and keys appear to be a conventional style, but no una corda or sustenuto. Thank you. Paul C
