There are also several versions of this style which bolts/clamps to the radiator support rods:

I have the one that Randy posted. It came from Macs for about $25. It works well and looks nice.

Just lay the hood back on itself. The hood props available are good for showing, and opening both sides at once, but are too restrictive to do any serious work, especially if you have side mount spares.
Yes I call that one the "head knocker", as I have helped others with their Model A and if you are not used to it and lean into the engine compartment, it will get you right in the fore head.
A fellow club member designed his own about 5 years back and made several for club members. His design is similar to the one sold by Snyder's.
Jim, Did you know Chief? (My Dad) He made a "stick" to hold the trans in high gear for a round trip on Route 66 in a ragged old '35 International Pickup. The "stick" was also used to hold up the hood. I don't remember if the gas guage worked or not. Bill W.Carl is right but my speedster has the '32 hinge so it won't lay back on itself. I made a gas gauge out of wood and made it long enough to prop open the hood. It is notched top and bottom to fit the hood and radiator braces.
