Vietnam era M1917 bayonet and scabbard questions?

[Melanie_Daniels]

That problem is the reason that st of the Siam P. 1907 sabbards have today the full metal scabbards. First they were devilverd with leather scabbards but this was no good idea.

I think that the Canadians only made the bayonets and the Americans used them with the WWII plastic scabbard.
