Those are some beautiful stocks man! I have 4 sets of John and Jennifer's myself, in Cocobolo, English Walnut, Kingwood and my newest set is Olive wood on my 629 Classic. John does fantastic work and the shape of his stocks fit me to the T.
Two of my favorite things on grips: that reddish hue and a glossy finish -really sets them off. Many of our members don't seem to care for glossy grips; I very much prefer them. Great job, Mr. and Mrs. Culina!
Made my wife a jewelry box from padauk. Over time it turned into a beautiful ebony with orange-reddish streaks. Great wood! BTW, your grips look awesome.
