Sorry , yes...I should have said Mod 42
Anyway, was told by one of my very reliable Canadian sources that the engraving in question was done by Ron Collins, probably at the time he was living in Canada.
Definitely not Rudolph Kornbrath
BTW, there is evidence of hammer and chisel work, can't see it in the pictures Roger but there are many progression marks throughout the scrollwork.
As far as engraving goes I do a bit...I'm more of a jack of all trades and master of none.
You can look at some of my previous posts and get an idea of what I like to tinker with.
All best,
CJ
