Don,
How hard is it to find a Newton in that sort of condition?
I would imagine an example like this would be pretty rare?

I think that the 1950's BSA featherweight rifles copied the Newton "look".
The BSA didn't have the same features as the Newton, but the styling is very similar.
The BSA didn't have the take down feature, nor the multiple bolt lugs, or the two trigger system.
The action lines, and stock are similar however.

The Newton looks like it was a very pupose built rifle, designed to work well in the hunting field.
That one sure is a beautiful example!
