Thanks for the info and I believe what you are saying is correct. I have a beautiful 1903a3 with a NZicon lend lease stock (NZ 8387, boxed RLB stamp, 5/43 barrel consistent with serial number). And I know in all probability someone swapped the stock out at some point, and that the barrel date is after RLB's career by a year or so. Just a puzzle why someone would take a beautiful stock off a legitimate NZ rifle and put it on a '03A3. This is what makes collecting these rifles so interesting and puzzling.
