<< Being new to the tubular world, and now recognizing that it may be hard to find these tires, how do you fix a leak around/by the valve stem?

With latex tubes that old that are questionable to start with, you probably ought to do a "tube-ectomy" and replace the whole tube. Open 4 to 6" TO ONE SIDE of the valve hole. Cut the new tube in an appropriate place and use the old tube to pull the new tube through the tire casing. when the new tube is positioned, fold a lip back so that about 1" of tube is doubled over. Apply glue to the exposed portion, insert the other end of the tube, unfold the one over the other and mash it around until the glue sticks. Be neat with the glue application so you don't glue the tube together internally. Apply talcum powder. Re-sew casing.
