Looks like a Briley sleeving job, certaintly not a Merrington, plus it has an American style low luster barrel blacking job-not the English high luster that "barrelbrowner" and others can do in England.
It is a shame as this is one of the finest original condition Premier actions I have ever seen. This gun was made in the time when the Premier sold for more than a Purdey SLE. HJ is right on on the max price it is worth. And at that price you could send it to England and have it sleeved and proofed. It deserves new barrels, though.
