I see by the brass plate in one of the photos the instrument was made in Belfontaine Ohio a place near to my heart: I learned to swim at a YMCA there in 1946. So let me add $25 to the fund to purchase this fascinating device. BTW and FWIW, the general look of the thing reminds me of a device that appeared in earlier editions of Bowditch (c. 1982?) in their listing of sight reduction methods. As I recall the Bowditch description had a picture of the device which appeared to be made of three white plastic plates that could be set to make a miniature navigational triangle. It looked like you set the two vertical plates to LHA and then aligned a third lateral plate with declination on one of the vertical plates and latitude on the other and read Hc from the lateral plate.
