Reproduco Unified Pipe Organ Survey

Operators Piano Company Study Project

Introductory Style Notes:

An Invitation to Send Accompanying Photographs

Pictures of the exterior of an instrument often allows us to identify case styles, control knobs, coin slots, art glass details, and other characteristics oftentimes not easily described through text alone. Moreover, snapshots of the interior mechanisms and any nameplates they may bear usually helps us greatly to identify mechanical characteristics that shed light on the mechanical evolution of an instrument, which helps us when developing dating guides. It is no stretch to say that photographs are an invaluable aid in detailing and understanding any instrument for which information has been submitted, and so please do consider sending photographs, albeit separately from the on-line form, but nonetheless augmenting the survey information.

Invitation to e-mail photographs corresponding to a survey submittal.
Please send photographs to:
