I sold a bunch of the earlier Whitworths back in the late 1970's or early 1980's; I don't exactly remember the years. I believe they were assembled in England from the CZ parts, possibly with English made stocks.

What I can tell you is that they are very good for the money. My present 375's are a Sako Safari Grade and a MarkX Alaskan. I stubbed my toe in not buying a Whitworth to replace its cheaper brother, Mark X, for $600.00 WITH a 1.5X5 Leupold...! I tried to beat the owner down another $50.00, and the guy next to me at the gun show laughed and pulled out the $600.00.

Every Interarms 375 I have shot(about 10 in all) has scratched the brass quite a bit. This was the only thing I could find fault with, however, and can be fixed by any decent gunsmith with a little stoning & polishing.

$675.00 is about the going rate for one. Be sure to check the stock for cracks! Take the barreled action out of the stock and LOOK!. If the seller won't let you, do not buy the gun. They tend to crack right near the bolt handle...forgot to mention that. If it is in nice condition in general, it is probably OK. Be sure to glass the action to prevent stock cracking. They ARE prone to that in the Whitworth configuration...not so in the rather clubby Mark X.

My Mark X shoots as tight as the Sako. I hope this helps.

Oh...the question 9,3x62 vs. 375 H&H...get one of each; its only money...

I shoot several 9,3x74r's in double rifles and in a 12/9,3 combo, and I shoot the 375's. The 9,3x74r and 9,3x62 have the same ballistics and get the job done on heavy thin skinned game. I have even taken cape buffalo with the caliber, but don't advise repeating that mistake.

For the most practical and useful caliber in the world, select the 375 H&H. It has so many dimensions to it and is legal for big five in most of Africa.
