On the block plane, check the iron and possibly the underside of the lever cap for markings. There could also be something cast into the base in front of the depth adjuster.
The jack plane looks to be a newer, lower end model, based on the plastic handles and phillips screws. Is the depth adjustment fork two piece steel? Also, check to see if the frog is stamped steel or cast iron. There may also be a makers stamp on the iron once the surface rust is removed.
Irons are replaceable, so that may not be an accurate indicator of the manufacturer, but it might provide a clue.
