This is a Silva Type 70 UNB Universal Hand Held Boat Compass made in Sweden. It is crafted from glass and plastic and designed for maritime use. The compass is manufactured by Silva, a reputable Swedish brand known for producing high-quality navigation instruments. This was my father's and is probably over 50 years old and was still in good working order last time he used it on his fishing boat. It would make a lovely addition to anyone interested in having this in their collection of maritime memorabilia.
