I'm buying an 03A3 barreled action in what looks just like a pre-64 Model 70 "Target" or "National Match" model stock. There's an inlet and holes for a handstop, beavertail fore end, extended pistol grip curve, etc.
The wood to metal is a close fit. I tend to assume that some aftermarket stock company knocked off an M70 target stock inletted for an 03A3. Or is it possible the two actions are that close and the builder used an M70 stock?
Incidentally the bbl is a Smith Corona 2-groove, the sight is a Lyman with target turrets. Good single stage trigger of some type. No speed lock but this was once somebody's match rifle. No photos yet, I'm waiting out the Washington state 10-day period that prevents me from acting in the heat of passion with a 70 year old match rifle.
