It DOES look like the Artec and the Allparts might be the same manufacturer.
But the 25+K ohms, double sidewinder coils, and adjustable pole pieces all tells me that these will sound almost the same as a genuine Gibson Mudbucker, they're definitely constructed the same way.
You might also seek a DiMarzio Model One, or there's a big ol Peavey Humbucker on the 'Bay now, too.
I went Sheehan on this one. Didn't have a chrome cover for it, so I bought a small black electronics "project box" and used the lid!
