It was a prototype gun made 1998 by Bob Serva with DJ Bushman being the designer and gun tester at that time with DW. I own the only one made, Serial number "460SM EXP 1" It was made before the S&W's 460, the story I got from DJ Bushman was that the S&W 460 was designed to compete with the DW 460.

Here is the only mention of it in print on the internet.

For those that have not seen what I have posted elsewhere here it is again. This information was given to me by DJ Bushman.
The 460 Supermag is a 45 win mag case stretched to 1.610 (supermag length). It can produce velocites that duplicate the new 460 S&W. The 460 S&W was produced to compete with the Dan Wesson but the 460 SM never made it into production because Dan Wesson did not have the money to fully put it into production. Boy they made a big mistake there.
During testing at the factory they shot experimental 200gr bullets at 2400 ft/sec with pressure at around 50,200 PSI. and they felt the round should operate at 50,000 with the proof loads at 70,000PSI.

Ok guys. I had to bump this old post, because this is a cool gun that DW only made one prototype example of. I have been surfing around the big 'ol WWW tonight & have found some more pics posted by 460smdave. Dave, even though you haven't popped in here in many moons, I hope you don't mind me sharing some of your pics. And a big congrats on scoring this cool gun!

That's all I've been able to find so far, but I tell ya, I'm drooling over here!
Although...I recalled seeing something about this in the "Models" tab at the top of this screen...hmmm. Wait a minute, this pic that Jody grabeed from DW's old site shows a different looking 460. Did they make two of these prototypes, or could that just a 4" shroud engraved with 460 stuff, slipped onto maybe a 44 frame or something??

That one is a .460 Rowland, different cartridge, I think. Originally developed as a high power cartridge for 1911 style autoloader
I went to a bookstore and asked the saleswoman "Were is the Self Help Section?" She said if she told me, it would defeat the purpose.

Ah yes, I believe you're absolutely right. Sorry, it was getting late last night & my wee brain wasn't thinking beyond point "a" any longer.
I'm also noticing today that the Rowland gun's frame & cylinder look a bit shorter too, more like a 44. I'd like to find the story on that one some day.
