303 Brit headstamp help

[blasted_saber]

Found three rounds of 303brit with the headstamp "K" and "67" opposite each other around the primer.

Any ideas what it is? Corrosive or not?

Thanks

I think (from recollection) that it would either be manufactured by Kynoch in Birmingham UK or Kirkee in India as both used the K....'67' should be the date of manufacture...'Should be non corrosive as well...Lots of 'should' as can't recall all details without more research

Kynoch in 1967. Large primer was / is corrosive. (Don't ask me how I know!)

The ones I have are softpoint in 10 round Kynoch sporting packages (Churchill, Cogswell & Harrison & the familiar red and yellow Kynoch.)
