Dan, thanks for the information. I think now I have seen some Sedgleys with 03 floorplates. Maybe the Enfield ones were more readily available. The difference between the two is minor, but I prefer the 03. On a slightly different note,over the past few years I've built some Mauser sporters using 03 magazine assemblies. They aren't mistaken for Blackburns, but they're a big improvement over the military Mauser ones.
