7.62 No4 MKI conversion question

[Surpmil]

I suspect it is not a DCRA conversion, but a gunsmith special using a Canadian Arsenals 7.62 barrel. DCRA conversions had a new serial number stamped onto the top of the bolt handle and a matching number stamped onto the receiver's right side just behind the barrel. A number of CA barrels were sent to England. It looks like Parker Hale got hold of at least one of them.

How does one explain the stylized maple leaf proof mark on the bolt and barrel ring then?

Notice that the "1" is in the same font used on other conversions. I haven't seen that font anywhere else on a Lee Enfield of any type.

These barrels did get fitted to odd actions now and then, but I've never seen one of those that had a conversion number or the maple leaf stamp.

We've been over the Parker Hale thing. See my previous posts.
