[CAUT] Baldwin specs

[Alan McCoy]

Hey Eric,

OK. The jack angle is actually begging for the spread to be moved out a bit,
which would be more toward spec. The hammer line is 5" as you suspected (and
knuckles are at 17mm). So what kind of magic are you working on these
actions with the too-short hammerline? This one needs hammers this summer
anyway, so assuming I can bribe well enough for some parts money, it'll get
done.
