Showing is the in 1932 patented Birglow cable operated handsignal. We wouldn't be suprised if it is possible to fill a midsize museum with alternative signaling devices. This one was bought new by the father of Willem Sas in Holland and was carefully kept by him. See the nice detailing of the manufacturers logo and be sure to check the original patent drawings. Elsewhere we found Birglow's 'night shift' (EarlyTech.com). (photos Willem Sas)
