I have seen a few of these on Gunbroker and can't find any other info on these. Does anyone have any clue who initiated the run on these?

The info I have gathered from Gunbroker is:

Part number: 0472
Cat number: KRNB-455WX
Stainless construction, Bisley grip/hammer, 45 Colt and 45 ACP cylinders provided, 5.5" barrel, black laminate grips.

This thing has got me all kinds of interested but I was wondering if any one new who is distributing them.
