I think we miss out on some of the issues of buying a #1 in any configuration.
The collectors value at times diminishes the market.
Not a lot of youngsters seeing the "need" for a $2000 collectable when they could get as mentioned, a tricked-out M-16 look-alike for that kind of money.
There was nothing wrong with chambering the S1L in .222 again, or having it available in .22 Hornet, .218 Bee, or .25-20, .25-30, or .256 Win Mag..
I know a handful of people interested in both the .250-3000 and the 300 Savage. As areas build-up, the moderate capacity cartridges are more than adequate, and leave the windowglass intact.
The #1 was offered in europe in the excellent 7x64 Brenneke, but when I spoke to SRCo about it in the early '90s, it was a matter of ordering (and pre-paying) for a run of 250... and we'll advise you if and when it's available.
I still have the ammo, never did see the gun.
I had what .280 Rem/7mm RemExp I could lay my hands on, and they sold like hotcakes, as I was a "known source". One sale begat another, as soon as it was seen at the range or in the deer camp.
Getting the #1 in 7x57 in was more problematic, there never enough.
Same for the #1B or #1V in 220 Swift.
I held but one .375 H&H and it was magnificent. Spectacular wood, for a black pad gun.
To sell these guns, I'd put one on the shelf, and have three buyers.
The .257 Roberts came and went, replaced by the .25-06, which didn't have the same appeal for some reason. It sold, but a 6 month dusting & cleaning was required.
That was 20 years ago, but I thoroughly doubt all those fellows ever saw the gun they lusted for, sitting in their rack.
I - personally, never had a cause for the .404, .416, .45-70 or .458 Win,
so those chamberings never sold to me or through me unless a specific order was placed.
I've seen the currently cataloged 9.3mm available locally, and it's still there waiting for a buyer.
The .257 Roberts (new and used) at the same venue have flown out ASAP.
I'd even go so far as to say the middle (.35) caliber hasn't been fully exploited in a #1: 348 Win, .35 Rem, 356 Win, 358 Win, 375 Win
Some would be better #1A, some #1S, some #1B...
Just sayin' if anyone's listening to the west of where I'm sitting.
