I havent seen some looking exactly like these, but have seen some VERY similar and had a wooden tri-pod. Possibly could have also been used on ship?--just a wild guess.
I know a guy who SHOULD know about these--he is: Richard J. Williams of Williams Militaria--he sells tons of these things. He is in I think, White Plaines, New York. I have a catalog of his in my car somewhere--ill see if I can find it and give you his contact info. I think he still has a website:
www.richardjwilliamsmilitaria.com or
www.williwmsmilitaria.com
Its been a few years since I last bought from him, but I do know his business has really taken off since then.
Hope this helps.
PS, are YOU now Andreas?
