Not worth the cost of shipping.
Back in the mid-ish 70's I had the Winchester shop do some work on a P64 Super Grade and I got a .375 H&H, from them, to play with. Both arrived in ID'd Winchester boxes at my local gun shop and I promptly transferred them into my soft cases after taking custody. After I declined to take the boxes, the gun shop owner asked me he could have them and I agreed. I mean, they are just shipping boxes. He takes them and makes a phone call. My rifles were behind the counter and I was still browsing when a guy comes in, greets the shop owner, gives him $50 cash dollars and leaves the store with the boxes. Gun shop owner told me the guy was a heavy hitter Winchester collector. $50 dollars back in those days would get you ~20 boxes of 12 ga. LB Federals, on sale, at Kmart. I think the H&H was a buck a round back then, as I recall.
I never thought much of those empty Winchester boxes. What I learned (it was a fast lesson) was, that I just wasn't paying attention... and someone else was.
Don't think I'll be need'n another lesson.
