I have been offered a Thomas Bland double. It is marked on the flats 275 along with nitro proof and other stamps. The gun is engraved with some stags as is the metal butt plate. The rifle is well used with bluing wear throughout. The stock is not cracked and has the usual bumps and scratches. The owner says it is a 7x57, is tight and barrels good. He has never shot the gun and did not know what regulated was. I have asked him to shoot it with two right and lefts and get back to me. The gun is a long way from me so I am unable to try it. I can find very little on the web for these guns. Anyone have an idea if they were good guns and their worth.
