help with 303Brit headstamps

[Workin Man]

I recently got a box of mixed milsurp ammo with a rifle I traded for (all 303 British). I have sorted it according to headstamp, here is a list of the headstamps:

- "HXP" "69" (I think this is greek surplus)
- "K57" "7"
- "RG" "58" "7" (also with "56", "60", "53" and "52")
- "GB1942" "VII" (bullet jackets are silver in colour, not copper)

I'm guessing the 2 digit numbers are all year of manufacture? Any other info, including if it has any collector value would be appreciated.

RG is Radway Green, Brit issue. HXP is Greek.

The other two are British as well; "K" is Kynoch, and "GB" is Greenwood and Batley, all loaded with Mk 7 ball.

Thanks guys. Any idea if the 1942 stuff is worth anything? I thought that since it was manufactured during the war it might be somewhat rare, but I don't really know.
