Nice Pre-War 70 Slamfire.
Here are my treasures:
1. Featherweight .243 Winchester with Redfield peep sight
2. Post-War 30/06 with Leuopold Pioneer 4X scope and adjustable mount
3. Pre-War .270 Winchester with a 330 Weaver and Korth Mounts
My Featherweight has a plastic or bakelight butplate. It's factory, so I guess we have both aluminium and plastic on the the Featherweights.
I've never seen a standard Pre-64 with an aluminium trigger guard, but now that I've said that, I'll bet someone has.
One and two will shoot MOA while number 3 (Pre-War .270) shoots 1 1/2 MOA for 10 shot groups. I think that is because the Korth mounts have a little play at the objective ring. I'll get 7 or 8 shots under an inch and then 1 or 2 will drop an inch out from the center of the group. That's with Hornady 130 grain interlockt bullets over 4831 powder. I could just shoot the standard 3 shot groups and call it a sub MOA rifle, but larger group size is statistically more accurate.
Funest of the bunch? The .270 with reduced loads.
Most useful? The 30/06 with the 4X scope.
Best for a youth or the wife? The .243. With the peep sight, it is truly a "Featherweight."
