Was the lucky recipient of a Bailey #3 with a Sweet Heart logo on the iron, "keyhole" blade cap, one piece (as opposed to stamped steel fold over) lateral blade adjuster, with frog adjustment, "hot airl balloon" front knob, no ring for it cast into the base, cast iron "wishbone" , frog adjustment screw and Type 15 & earlier frog, no rib cast into the front and back of the body, only one patent date in body behind the frog. Sweet little thing which will go well with the #4, 2 #5s, #6 and #7 I've already acquired (and actually have used_.
That's the neener/gloat.
While searching for info to date it I found this site that goes beyond The Flow Chart. Worth checking out if you're interested in dating a Bailey/Stanley plane you have. Good pictures sure help.
