I think it would be safe to assume your abyonets are original. French bayonets in general are not valuable enough to copy, unlike German ones. Some models were shortened (for some reason or another, I'm sure the experts can elaborate upon that) when recalled to the armoury, and re-pointing a broken piece was regularly done also. There was a war on you know, metal was scarce.
These pieces will certainly be of interest to collectors of french weaponry, and interest in WWII stuff is increasing.
