I don't think it was WW 11 fittings at all just a combat cover that let him carry it into. From my experience it looks like the brass hanger was added like Brian said, they do not always ruin saya and often slide off with little work, adding a kurikata is little work for a sayashi, you should be able to tell the quality of the lacquer from what you can see under the cover at the koguchi. Both B and S make good points but don't count out what you have, IMHO late shinshinto mounts with possible shinto blade that remands to be seen.
