7.62 No4 MKI conversion question

[Surpmil]

Surely if it was stamped Parker Hale, then they carried out the conversion (Unless some dealer faked it).

Parker Hale sold a quantity of No4 Mk2 actions, or perhaps whole rifles, at some point in the 60s, as several in the 1954/55 range have turned up here as genuine DCRA conversions. I've had two over the years. The marking being thus:

Parker-Hale

Small stamping right on the barrel ring top centre.
