After being involved in the restoration business for over forty years, we at Colonial Instruments believe in complete disclosure in representing the instruments accurately and acknowledging any restoration. In contrast to the practices of some auction houses and dealers who arrange the photograph of the instrument in an attempt to obscure any shortcomings and avoid mentioning any repairs or restoration, we feel this is a character as well as a business flaw.  We refuse to take part in these tactics and will go out of our way to accurately represent the instruments we offer for sale to the best of our knowledge. The true test of a person's integrity is when full disclosure of the truth costs him financially.

We have found that properly replicated pieces, signed and dated, built from accurate historical data, do not have an appreciable impact on the final selling price of an instrument.
