About a year before they closed down their NJ operation,Navy Arms had about a half dozen Whitworths for sale in .375 Weatherby (not .378).They also had another 3-4 barreled Whitworth actions in the same chambering.The rifles went for $175.00,the actions $125.00.So at least a few were also made in that chambering.Navy Arms regularly had oddball stuff on hand that you wouidn't find elsewhere.
I bought one of the rifles along with a matching 7x64.Two months later a guy gave me $400.00 for the .375 and I let it go.Been sorry ever since.Never got the reloading stuff together to make up some .375 Weatherby,so never did shoot any .375 H&H in it to fire form.
