A few things I wanted to get straight regarding DCRA No.4’s.

Were all the conversions done centrally, i.e. by the government or did the Canadianicon firearms trade get involved?

Have most of the original .303 versions (an assumption here that most started out as .303) been converted to 7.62mm?

Were there specifications laid down regarding things like the use of tunnel/globe foresights for competition use?
On this question I’m wondering if things like the length of a tunnel foresight were governed?

Rear sights: Is one more common than the other?
For instance in the UKicon on L39A1’s I tend to see a greater number of AJ Parker 4/47’s than I do P-H 5c’s.

Some rifles of Canadian origin, and I think of Canadian specification do not appear to be officially marked, is there a story behind unmarked DCRA rifles?

If you can help me with the above it would be appreciated; I would just say that retirement is now kicking in and research is just kicking off!
