Plus one for Huvius' comments

I have one in .450/400 3 1/4" Nitro made by Thomas Turner with Krupp steel barrels
Thomas Turner made many/quite a few?? of these Farquharsons but agree wuth Huvius about Phillip Webley

Without telling you how to suck eggs, these rifles are not that heavy and wuth a .470 full Nitro load
recoil may be a little "stout"

Good luck shooting it, you certainly got a bargain (nice engraving) you would pay a lot more here in the UK
