I don't recall for certain if I saw the movie of, "The Beastmaster." How old is it? I did see a few episodes of the TV series, but don't recall the swords well, so they were probably typical fantasy sorts.
The TV series was pretty dismal, but they did have Aussie actress Lara Cox in at least one ep. Lara did some work in other series for the same producers, including nine episodes of the better financed, "Sir Arthur Conan Doyle's The Lost World", where she played Finn for much of the Third (final) season. I kinda fell in lust with cute Finn, and she stars in most of my 28 Fan Fiction stories based on that program, made from 1999-2002.
You can also see Lara (again faking a US accent) in the DVD movie,, "The Marine 2". Recommended: it's a better film than most action movies. Lara plays the hero's wife. It has no connection to the Marine 1, which stank, by comparison; different cast and circumstances...
Oh: you asked about that knife. See what happens when I get to thinking of Lara Cox? Sorry.
I have heard of the maker, somewhere. Can't be sure where, and I was a writer for virtually all of the knife titles for many years. But I have seen pics of his knives.
What I can tell from your photos is that he was almost certainly a pupil or fan of John Nelson Cooper, who made many knives for Hollywood celebrities. Can't recall which movies he had knives in, but there were some. Cooper was a very well known maker. He isn't listed where you'd normally check for custom makers, in Digest Books's big annual volume, "Knives." That's because he's been deceased for some years.
I also checked some editions of that title for Anselmo. I think his first name may have been Victor. But I found no listing, and no Anselmos at all. Possibly, you'd have better luck if you post on some knife forums. Let us know what you learn.
The knife does look good. I suspect that it's well made and quite functional, if not especially collectible. If you don't think it'd affect whatever collectible value it may have, I'd polish that sheath and take care of it. If permitted in your jurisdiction, this should be a very good heavy duty camp and survival knife. Military personnel may or may not be allowed it, depending largely on local commanders' policies. But most here probably know things like that...
