Don't think they'd help you Ed. Its 10 tpi so the metric one probably wouldn't fit down into the threads enough to check the angles if it is metric. Grind a piece of sheet metal to fit the gauge you have, if it fits the lead screw its standard acme, if not use a protector to get 30 get and see if it fits.
Free advice is worth exactly what you payed for it.
