Acquiring a correct No32MKII or MKIII scope and mount is a $1700USD plus proposition. By all means, secure a real scope and mount if you can. There is an alternative. Repro mounts are available. A vintage Weaver K4 blued steel tube is the correct one inch diameter, about the same 12.3 inch length and costs around$100. It is well proportioned for the gun. A Kollmorgen 4X is another nice substitute.
