Need A New Co2 Pressure Gauge

[bullheaduk]

I need a new gauge for a D&D freshwater co2 setup. Anyone know where to buy one from please. I have looked on their website and they don't have them listed.
I just need the gauge that screws into the regulator itself.
Or if anyone has a spare i would gladly buy it from you and pay postage.
Thanks
