Sounds exactly like the ones our officers wear at the SCOTS DG. Wouldn't know where to get one myself, and I'm not going to ask where I can get one either at the risk of sounding like some wannabe. Sorry!
I've got a 37 pattern belt with brass fittings knocking about somewhere in the garage. The only trouble with them is that all the hooks and things get snagged in your JHW but otherwise bloody smart if the brasses are gleaming.
