I have a 20 bore tisdale (of NZ) sidelock, decent gun. Not a great gun. Like most Brit guns, judge them for the actual merits and condition of the gun, not the name. As to how do you know if it is safe, a visual inspection combined with a bore gage and a good knowledge of proofs goes a long ways, or you could have a guy who is familar with Brit doubles give it a look over.
