Remington No 1 Creedmoor

[Fogman01]

I am interested in finding an original Creedmoor rifle in shootable condition. The Sharps originals are out of my price range. I have a couple of Shiloh Sharps and love the BPCR shooting. Just getting into matches now. I was thinking of a Remington Rolling Block No1 Creedmoor in excellent condition I saw at a collectors website. Rolling blocks were used in the original Creedmoor matches. This one seems to have everything even the little wedge piece in the bottom of the pistol grip and the original sights. But I have looked at past auctions of Julia's and some other places and it would appear that $6900 is a bit high for this model. What caliber is "44S". Looking at other No 1's it appears to mean 44-77. But maybe 44-90???? Bottle neck - straight?
And what would be a range for the price of Remington rolling block No 1 Creedmoor?

Thanks for any help.
