Fellow in the office, approached me today and asked if that was a factory caliber. Does anyone here know?

THanks,

Win. offered the 375 H&H, but not the 375 wby in a pre-64. If it is a pre-64 in 375 wby, then it has been rebarreled or rechamered, ruining any collector value, but it may still be a $700 to $1000 gun.

Many .375 H&H were rechambered to .375 Wthby and many 300 H&H were rechambered to 300 Wthby...it was unfortunatly a very common occurrence. I picked up my pre-64 300 H&H for $300 several years ago because it had been rechambered. Found a "new" factory H&H barrel and had it redone. Not much in the way of collecting, but a great shooter. My guess is that this 375 Wthby is one of those...
