Markings on WWII Wilkinson P1907's

Hi,

Quick question: why do some Wilkinson WWII production P1907's have an 'S294' marking in addition to 'WSC' and some do not? I own one that falls into the latter category.

Thanks,
Mark

the WSC S294 are contract bayonets for the LAnchester SMG, the others are not

Ah. That's a pity. I did actually buy it to go with my Lanchester.

Who were the non-coded ones made for?

Thanks,
Mark
