Headstamps date request

Hi,
Im looking for a manufacture date for this head stamp and any company information.
Thanks in advance for any assistance.

From the use of “England” rather than Great Britain and stamped in that fashion would probable place it 50’s and onwards. Looking at what cartridges I have in the collection, not many actually have that head stamp (which surprised me) and the firms that had it are from the period I said.
Looking at the cases and print none give a make and I have not had chance to look in any books.

Sorry that is not much help.

Thanks for your help. I appreciate it!
