Looks like a very nice 1\4 to near wedge FR. I have a couple of these and they are fine shavers. Mine are fairly hard and take a little more time to hone, but the results are worth the effort. Being a near wedge, the edge will be a less fragile than if it were a full hollow. The date of manufacture is probally before 1891 as only the city and not the country ( England ) is stamped on the shank. Injoy your FR as they are among the top shavers from England. Very Best and Happy Shaving, wildhog
