Very little information is available about the DW Karn company. An organ with the serial number 19934 can only be placed to have been manufactured between 1886 and 1890.
The Bridgeport Organ Company operated in Bridgeport, Connecticut (USA) from the late 1870ies to around 1905. There are very few records left, so deducing age from serial number is impossible. But you could open the casing and remove a reed - most reeds have the year of manufacture stamped onto them. Our Bridgeport organ is serial number 39018 and was made in 1888 (numbers were not necessarily used subsequently, though).
