I was in the Hazelwood (St Louis) Cabelas today. On the racks were 2 beautiful Danish Rolling blocks, both tagged at $700. I don't know what a good price is for these, but I do know at this store they discount 10% of the tag price as soon as you set down. And then you negotiate. These also both have PRISTINE bores, and will work with slightly shortened, neck sized 45-70 brass (51mm).
They were also tagged as maker and caliber unknown, but I knew!
They do not appear on the website.
