I have been searching for some 1942 MW plenty of latter stuff but the early YOP is hard to find.
Here is my 303 rounds collection I was sorting it out out a while ago not shown is a 100 rounds of MF 59 MK VII that's in a S-26 milk tin.
Different manufacturers, some very early MK VI stuff have a couple of MKII and un stamped 215gn rounds think they are BP not sure, bit of everything trace, A.P and incnd somewhere there also some linked 303 got 100 links from fleabay years ago have not seen them advertised since.
I have on hand (Not shown) @450 re-loaded rounds one bandoleer has the early stripper clips from WWI I save that for when I shoot the 1916 5MD MkIII once a year the fellas always ask have I got any spare WWI clips. (Picked up 50 pieces years ago on flea-bay)
Going to be pretty hard to add to it now as they have stopped the live collectible stuff being sold at our military fairs here in West Au deactivated only.
