Американские коллеги поправили, скорее 60-е, фирма Voit, ножны с ножом родные, Swimaster профессиональная серия водолазных аксессуаров. Пока инфы по тому, кто приобретал нет, продукция коммерческая, выпуск с позолотой мемориальный номерной, мне впаривали, что для кого-то, кто во Вьетнаме воевал. Вот все, что Фрэнк мне ответил.
Hello Andre,
Voit is a commercial maker of diving equipment that is popular here in the US. Your knife was made after 1957 when AMF (also shown on your knife)purchased Voit. They created the Swimaster line of professional dive equipment. Voit scuba gear had been featured in the TV series Sea Hunt(1958-61); and movie and TV series versions of Voyage To The Bottom Of The Sea (1961; and 1964-68 respectively) where it was included in the series' closing credits; and both got a tie-in in the James Bond movie Thunderball (film) who used Voit equipment.
I do not know of any Special Forces units using this knife but it is possible. They have money to buy equipment off the record and often do not keep books on what they have or what they use.
Sorry I could not be more specific for you.
All the best
Frank Trzaska
